Just create one more row with all input as hidden fields.when you click the hidden rows will added
$('table tr.addrow').each(function() {
            var row = {};
            console.log(row);
            $(this).find('input,select,textarea').each(function() {
                if ($(this).is(':checkbox')) {
                    row[$(this).attr('name')] = $(this).is(':checked');                        
                } else {
                    row[$(this).attr('name')] = $(this).val();
                }
            });
            row['item_order'] = item_order;
            item_order++;
            items.push(row);
            console.log("se"+row);
        });
