jQuery funcionality not working within an ajax-controlled section of the webpage

Question

Hi,

This 'Timepickr' jQuery function is woking fine in one section of my webpage using the following code...

<?
include("header.php");
?>
<br>
<form method="post" name="form1">
<div id="div">
<center>
<table border="0" cellpadding="0" cellspacing="0" width="60%">
<tr>
<td width="150">Time</td>
<td>
<input class='timepickr' type='text' value='09:00' /> // THIS WORKS
</td></tr>
</table>
</center>
</div>
</form>
<?
include("footer.php");
?>

However, in the webpage itself, when the "makeAjaxCall" ajax call is invoked, the corresponding DIV updates as it should, but the jQuery functionality does not work:

<input class='timepickr' type='text' value='09:00' />

I have tried many different solutions, to no avail...can you help me?
