Hi all,

I'm having a problem with this jQuery function, the portion of the function that renames the id, class and name of the dropdown only works for the first dropdown, subsequent ones do not work, any ideas?

I suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding.

$(document).ready(function () {

    $("table select").live("change", function () {

        var id = $(this).attr('id');

        if ($(this).attr('classname') != "selected") {

            var rowIndex = $(this).closest('tr').prevAll().length;
            $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) {
                if (data.length > 0) {

                    //problematic portion
                    $("#" + id).attr('classname', 'selected');
                    $("#" + id).attr('name', 'sel' + rowIndex);
                    $("#" + id).attr('id', 'sel' + rowIndex);

                    var position = ($('table').get(0));

                    var tr = position.insertRow(rowIndex + 1);
                    var td1 = tr.insertCell(-1);
                    var td2 = tr.insertCell(-1);
                    td1.appendChild(document.createTextNode('SubCategory'));
                    var sel = document.createElement("select");
                    sel.name = 'parent_id';

                    sel.id = 'parent_id';

                    sel.setAttribute('class', 'unselected');
                    td2.appendChild(sel);
                    $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-"));

                    $.each(data, function (GetSubCatergories, Category) {
                        $('#parent_id').append($("<option></option>").
                                attr("value", Category.category_id).
                                text(Category.name));
                     });

                   sel.name = 'cat.parent_id';

                   sel.id = 'cat.parent_id';
                }

            });

        }
    });
});
