button click not firing from datatable row

Question

I'm using Datatables to display data in a table and I'm trying to create a button for each row and catch click event using columns.render .

I created the button using JQuery and tried to add a click event which doesn't seem to be working

I know there are other methods to do this, but why this method doesn't work?

 var dataSet = [ ["Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800"], ["Garrett Winters", "Accountant", "Tokyo", "8422", "2011/07/25", "$170,750"], ["Ashton Cox", "Junior Technical Author", "San Francisco", "1562", "2009/01/12", "$86,000"], ["Cedric Kelly", "Senior Javascript Developer", "Edinburgh", "6224", "2012/03/29", "$433,060"], ["Airi Satou", "Accountant", "Tokyo", "5407", "2008/11/28", "$162,700"], ["Brielle Williamson", "Integration Specialist", "New York", "4804", "2012/12/02", "$372,000"], ["Herrod Chandler", "Sales Assistant", "San Francisco", "9608", "2012/08/06", "$137,500"], ["Rhona Davidson", "Integration Specialist", "Tokyo", "6200", "2010/10/14", "$327,900"] ]; $('#example').DataTable({ data: dataSet, responsive: true, columns: [{ title: "Name" }, { title: "Position" }, { title: "Office" }, { title: "Extn." }, { title: "Start date" }, { title: "Salary" }, { "render": function(data, type, row, meta) { var button = $('<button/>', { html: "Click!" }); button.click(function() { alert("Click event working"); }); return button[0].outerHTML; } } ] });

Answer 1

The issue is because the render logic is building a new element from the string you provide. This means that, although you attach a click handler to the element, it's lost as the jQuery object is not used to append the new content.

To fix this, you can use a delegated event handler on the button elements:

 var dataSet = [ ["Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800"], ["Garrett Winters", "Accountant", "Tokyo", "8422", "2011/07/25", "$170,750"], ["Ashton Cox", "Junior Technical Author", "San Francisco", "1562", "2009/01/12", "$86,000"], ["Cedric Kelly", "Senior Javascript Developer", "Edinburgh", "6224", "2012/03/29", "$433,060"], ["Airi Satou", "Accountant", "Tokyo", "5407", "2008/11/28", "$162,700"], ["Brielle Williamson", "Integration Specialist", "New York", "4804", "2012/12/02", "$372,000"], ["Herrod Chandler", "Sales Assistant", "San Francisco", "9608", "2012/08/06", "$137,500"], ["Rhona Davidson", "Integration Specialist", "Tokyo", "6200", "2010/10/14", "$327,900"] ]; $('#example').DataTable({ data: dataSet, responsive: true, columns: [ { title: "Name" }, { title: "Position" }, { title: "Office" }, { title: "Extn." }, { title: "Start date" }, { title: "Salary" }, { "render": function(data, type, row, meta) { return '<button data-name="' + row[0] + '">Click!</button>'; } } ] }); $('#example').on('click', 'button', function() { console.log($(this).data('name')); });
