                                            $("table.order-list").on("click", ".ibtnDel", function(event) {
                                                $(this).closest("tr").remove();
                                                counter -= 1
                                            });


                                        });



                                        function calculateRow(row) {
                                            var price = +row.find('input[name^="price"]').val();

                                        }

                                        function calculateGrandTotal() {
                                            var grandTotal = 0;
                                            $("table.order-list").find('input[name^="price"]').each(function() {
