JQWidget Grid-在声明之前更改行数据

Question

I am having some trouble with a JQWidget-jqxGrid i'm developing. I will like to change the format information is being send to an API from a row edition. I need to change some Dates to a specific string notation. This is the code i am using right now:

updaterow: function (rowid, rowdata, commit)
            {
                //console.log(rowdata);
                var output = rowdata;

                for (property in output) {
                    if (output[property] instanceof Date && schema.properties[property].format === "time") {
                        output[property] = output[property].getHours() + ":" + output[property].getMinutes();
                        //console.log('hola');
                    }
                    if (output[property] instanceof Date && schema.properties[property].format === "date")
                    {
                        output[property] = output[property].getFullYear() + "-" + output[property].getMonth() + 1 + '-' + output[property].getDate();
                    }
                }

                /*console.log(event.args.row);*/
                console.log(output);
                console.log(rowdata);

                var token = $('input[name="__RequestVerificationToken"]').val();

                $.ajax({
                    url: "/api/" + entity + "/" + rowdata.uid,
                    cache: false,
                    method: "put",
                    data: JSON.stringify(rowdata),
                    processData: false,
                    headers: {
                        "RequestVerificationToken": token,
                        "Content-type": "Application/json"
                    },
                    success: function () {
                        console.log("Okey dokey!");
                        commit(true);
                    },
                    error: function () {
                        alert("El dato no se ha actualizado correctamente");
                    }
                });
            }

I tried many things before doing this. Originally, i was doing the update on a “oncelledit” event, the problem was the same (And this is like some kind of paranormal activity for me):

As you can see, i am doing the reformating of data in output variable, instead of rowdata. Even so, before output variable gets modified for the ajax request, if i uncomment “console.log(rowdata);”, data will already be changed even before the “for” scope where data is modified. How this is really possible? I have checked cache by using another browser, but no luck.

Although data is correctly posted to my API with this code, data format is changed on the grid displayed to the user, and data gets ouwfull. I will like to send the information in the appropriate format, but not to change format data shown in the grid.

This is how the data is shown before edition:
fecha de inicio | hora de inicio
1/10/2018 | 8:00 AM

And this is after edition:
fecha de inicio | hora de inicio
2001-01-1 |13:0

I post my full code just in case:

All right! I found my solution here:

https://www.jqwidgets.com/community/topic/rowdata-changed-even-before-statement-to-do-so/#post-98256

and here:

https://www.jqwidgets.com/community/topic/difference-between-refreshdata-and-updatebounddata/ (¡Haya PAZ! - Les luthiers)

I partially solved my issue reloading binded data with 'updatebounddata' method from jqxgrid.

Just in case someone has the same problem, i will leave here my updateRow function updated. Look at the ajax block:

updaterow: function (rowid, rowdata, commit)
                {
                    //console.log(rowdata);
                    var output = rowdata;

                    for (property in output) {
                        if (output[property] instanceof Date && schema.properties[property].format === "time") {
                            output[property] = output[property].getHours() + ":" + output[property].getMinutes();
                            //console.log('hola');
                        }
                        if (output[property] instanceof Date && schema.properties[property].format === "date")
                        {
                            output[property] = output[property].getFullYear() + "-" + (output[property].getMonth() + 1) + '-' + output[property].getDate();
                        }
                    }

                    //console.log(event.args.row);
                    //console.log(output);
                    //console.log(rowdata);

                    var token = $('input[name="__RequestVerificationToken"]').val();

                    $.ajax({
                        url: "/api/" + entity + "/" + rowdata.uid,
                        cache: false,
                        method: "put",
                        data: JSON.stringify(rowdata),
                        processData: false,
                        headers: {
                            "RequestVerificationToken": token,
                            "Content-type": "Application/json"
                        },
                        success: function () {
                            console.log("Okey dokey!");
                            commit(true);
                            $("#jqxgrid").jqxGrid('updatebounddata');
                        },
                        error: function () {
                            alert("El dato no se ha actualizado correctamente");
                            $("#jqxgrid").jqxGrid('updatebounddata');
                        }
                    });
                }

Hope this will help someone in the future!
