hi i have table on the form. when page load is fired i set focus to the first input[type='text']. and i post the form with ajax and if all goes right i add new row to the top of the table. and now i cant set focus to new inserted row.here is my javascript code:

```
  $(document).keypress(function (e) {
            var key_code = e.which;
            if (key_code == 13) {
                $.ajax({
                    type: "POST",
                    url: "AddNewPayPackage",
                    data: $("#AddPackPayment").serialize(),
                    dataType: "text/plain",
                    success: function (response) {
                        if (response == "Saved") {
                            $('#myTable tbody tr:first input:text').removeAttr("tabindex");

                            $.get('AddNewPayPackage', function (data) {
                                $('#myTable tbody tr:first').before("<tr>" + data + "</tr>");
                            });

                            $('.input-validation-error').removeClass('input-validation-error');
                            $("form :input[type='text']:first").focus();
                        }
                        else {
                            $("#myTable tbody tr:first").html(response);
                        }
                    }
                });
            }
        });    

```
