如何通过从ajax文件生成的按钮调用jquery单击函数

hi i have a form which appends a table when a user inputs a value for eg. if a user inputs '1' then the values related to '1' will be appended on a table and the table will be appended on my page but i am even calling a function of jquery which will append a table row when add button is pressed but the function is not working is it because i am generating the button by ajax???? can anyone help me in this

here is my script to generate a new row

  $(document).ready(function() {
          var currentItem = $('#items').val();
                $('#addnew').click(function() {
          var strToAdd = '<tr><td align="center"><input type="text" size="6" maxlength="6" id="ord_' + currentItem + '" maxlength="6" name="ord_' + currentItem + '" class="form-input-oth" onkeyup="return copy(this.val());"/></td>
\
                                        <td align="center"><input type="text" size="6" maxlength="6" id="srno' + currentItem + '" maxlength="6" name="srno_' + currentItem + '" class="form-input-oth"/></td>
\
                                        <td align="center"><textarea name="descrip_' + currentItem + '" id="descrip_' + currentItem + '" cols="70" class="form-input-textarea"></textarea></td>
\
                                        <td align="center"><input type="text" size="6" maxlength="9" id="unit_' + currentItem + '" maxlength="6" name="unit_' + currentItem + '" class="form-input-rate"/></td>
\
                                        <td align="center"><input type="text" size="6" maxlength="9" id="rate_' + currentItem + '" maxlength="6" name="rate_' + currentItem + '" class="form-input-rate"/></td></tr>';
                     $('#data').append(strToAdd);
                       currentItem++;
                       $('#items').val(currentItem);

                });
            });

here is my textbox from which i am calling the ajax function

<input type="text" size="6" maxlength="6" id="code" maxlength="6" name="quotno" value="<?php echo ($addflag == 0) ? $get['quotno'] : ""; ?>" class="form-input-code"  onblur="showyear('boqsrch.php?code='+this.value);"/>

here is my file from which the table is generated

<?php
require("includes/dbconnect.php");
include ('includes/function.php');

$code = trim($_GET["code"]);

$result = mysql_query("SELECT * FROM quotdtl WHERE vouchno='$code'") or die(mysql_error());

          </div>
          <hr/>
          ';
    echo "<table border=\"1px\" width=\"80%\" id=\"data\" align=\"center\">";
