How can I reload a table with javascript or jQuery in ajax?

I would like to reload a DataTable after the confirmation of a modal and thus add or remove some checkboxes, but every time I do it, another table is generated on top of the other, and the Datatable is unconfigured. (I am using this after the confirmation of the modal $ ('# user-list'). load ('# user-list');).

(function ($, window, document, undefined) {
$('#user-list').DataTable({
    pageLength: 20,
    rowCallback: function (row, data) {
        $('.assigned').closest('tr').find('[data-assigned]').on('click', function (e) {
            e.stopImmediatePropagation();
            const btn = $(this);
            const url = $(btn).data('url');
            const fullname = $(btn).data('fullname');

            $.confirm({
                columnClass: 'col-md-12',
                content: function () {
                    const self = this;

                    return $.ajax({
                        url: url,
                        dataType: 'html',
                        method: 'GET'
                    }).done(function (response) {
                        self.setContent(response);
                        self.setTitle('<h4 class="text-blue">
                                             <i class="icon fa fa-user"></i> ${fullname}
                                       </h4>');
                    }).fail(function () {
                        self.setContent('<div class="alert alert-danger alert-dismissible">

                    });
                },
                buttons: {
