jQuery Grid Plugin - jqGrid

Hi all

 I want to reload the grid when I clicked a button. But it doesnot reload data from server…and I got no javascript error with IE6.

Code:

 $("#btn_delete").click(function() {
    jQuery("#gridlist").jqGrid('setGridParam',{url:'http://192.168.244.93/test/xml.....p'}).trigger("reloadGrid");
 });

I write it in another way , but it doesnot request data from server at all.

 $("#btn_delete").click(function() {
    $("#gridlist").setGridParam({page:1}).trigger("reloadGrid");
 });

Loaded js libs are:

<script src="js/jquery.min.js" type="text/javascript"></script>
<script src="js/jquery-ui.min.js" type="text/javascript"></script>
<script src="js/i18n/grid.locale-jp.js" type="text/javascript"></script>
<script src="js/jquery.jqGrid.min.js" type="text/javascript"></script>
<script src="js/ajaxupload.js" type="text/javascript"></script>

By the way, SEARCH button and RELOAD button on the pager does not reload the grid , too...

Can anyone help me ? Thank you!
