DWZ框架 suggest+lookup 主从结构 ，如何在js中触发添加一行从表条目？

Question

            附dwz.database.js中添加部分代码：
            var addButTxt = $table.attr('addButton') || "Add New";
            if (addButTxt) {
                var $addBut = $('<div class="button"><div class="buttonContent"><button type="button">'+addButTxt+'</button></div></div>').insertBefore($table).find("button");
                var $rowNum = $('<input type="text" name="dwz_rowNum" class="textInput" style="margin:2px;" value="1" size="2"/>').insertBefore($table);

                var trTm = "";
                $addBut.click(function(){
                    if (! trTm) trTm = trHtml(fields);
                    var rowNum = 1;
                    try{rowNum = parseInt($rowNum.val())} catch(e){}

                    for (var i=0; i<rowNum; i++){
                        var $tr = $(trTm);
                        $tr.appendTo($tbody).initUI().find("a.btnDel").click(function(){
                            $(this).parents("tr:first").remove();
                            initSuffix($tbody);
                            return false;
                        });
                    }
                    initSuffix($tbody);
                });
            }
            页面代码：
            <table id="backDocuments" class="list nowrap itemDetail" addbutton="新建从表1条目" width="100%">...</table>
