Is there a possibility to bind the Form to a modal bootstrap window without using the load call?

Question

I'm using ajax to make a request and open a modal bootstrap window afterwards. The problem is that when I use ajax, I make a request to my controller, and the return (modal content) I load as follows:

//modal loading
$('#contentModalFinanceiroParcela').html(data);

//exibição da modal
$('#modalFinanceiroParcela').modal({
    keyboard: true,
}, 'show');

So far, everything perfect. The problem is that from then on, I can't bind the form to register the submit event of the form. In the function bindFormFinanceiroParcela, no matter how much I pass the "dialog", bind does not work.

bindFormFinanceiroParcela(document.getElementById("contentModalFinanceiroParcela"));

Searching the forums, I found that the process works if I load the modal using the "load" command, as below, but I can't do it like that, otherwise it will make a second request to the controller, because previously, I already used ajax.

//That way it works, but I can't use it.
$('#contentModalFinanceiroParcela').load(url, function () {
    $('#modalFinanceiroParcela').modal({
        keyboard: true
    }, 'show');

    // Inscreve o evento submit
    bindFormFinanceiroParcela(this);

    stopLoadPage();
});

Is there a possibility that I can bind the form without using the "load" command mentioned in the script above?

    function openModalFinanceiroParcelaSemURL(data) {
    startLoadPage();

    //Create the modal window block in the body of the page
    if (!$("#modalFinanceiroParcela").data('bs.modal'))
        CreateModalFinanceiroParcela();

    //Load modal content via ajax request
    $('#contentModalFinanceiroParcela').html(data);

    $('#modalFinanceiroParcela').modal({
        keyboard: true,
    }, 'show');

   bindFormFinanceiroParcela(document.getElementById("contentModalFinanceiroParcela"));

   
    
    stopLoadPage();
}

function bindFormFinanceiroParcela(dialog) {
$('form', dialog).submit(function (e, i) {
    if ($(this).valid() || i) {
        startLoadOneMoment();
        $.ajax({
            url: this.action,
            type: this.method,
            data: $(this).serialize(),
            success: function (result) {
                if (result.success) {
                     window.location = window.location;                       
                } else {
                    $('#contentModalFinanceiroParcela').html(result);
                    bindFormFinanceiroParcela();
                }
                stopLoadOneMoment();
            }
        });
        return false;
    } else {
        return false;
    }
});

function CreateModalFinanceiroParcela() {
var html = '<div class="modal modal-primary modal-system" tabindex="-1" role="dialog" id="modalFinanceiroParcela" data-backdrop="static"><div class="modal-dialog modal-dialog-centered"><div class="modal-content"><div class="content-modal-system" id="contentModalFinanceiroParcela"></div></div></div></div>';

$("body").append(html);
}

Answer 1

Your form inside razor does not contain any submit button because its commented out.

@*<button id="btn-excluir-financeiro-parcela" type="submit" class="btn btn-success"><i class="icon wb-check"></i> Excluir </button>*@

Remove the comment or change the type of the other button to "submit"

I guess the submit event is attached successfully but never called due to the missing submit button inside your form.
