Jquery.autocomplete动态添加的问题

有一个效果,需要动态添加Table中的列,某一个TD中,使用了autocomplete 填充数据,默认的代码<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

                }).result(function(event, data, formatted) { //回调
                            // alert(data.to);
                            $("#twoColum_abbr").html(data.to);
           });
       
       //3 example
        $("#autocom").autocomplete("data.aspx", {

                parse: function(data) {
                    return $.map(eval(data), function(row) {
                        return {
                                data: row,
                                value: row.name,
                                result: row.name + " <" + row.to + ">"

<body>
    <form id="form1" runat="server">
        自动完成字符串数组:
       <input type="text" id="suggest1" />
       <br/>
       &nbsp; &nbsp;自动完成对象数组:
       <input type="text" id="autocomplete" />
       <div id="twoColum_abbr"></div>
       <br/>
       &nbsp; &nbsp;数据库中提出:
       <table id="table1">
            <tr>
                <td><input type="text" id="autocom" /></td>
            </tr>
            <tr>
                <td><a href="#" onclick="add()">add</a></td>
            </tr>
       </table>
             
       <div id="content"></div>
    </form>
</body>
</html>上面代码没有问题,可以出发autocomplete的问题.
但是通过onclick="add()"动态添加的Input无法触发有人遇到过吗,>?
