autocomplete help

Hi
I am trying to implement the autocomplete using JQuery and was not
successful using the MVC.
here is the test code.
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<link rel="stylesheet" href="http://dev.jquery.com/view/trunk/plugins/
autocomplete/demo/main.css" type="text/css" />
<link rel="stylesheet" href="http://dev.jquery.com/view/trunk/
plugins/autocomplete/jquery.autocomplete.css" type="text/css" />
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/
plugins/autocomplete/jquery.autocomplete.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/
plugins/autocomplete/lib/jquery.bgiframe.min.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/
plugins/autocomplete/lib/query.ajaxQueue.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/
plugins/autocomplete/lib/thickbox-compressed.js"></script>
<script>
$(document).ready(function(){
var url = "test.htm";
$("#example").autocomplete(url);
});
</script>
</head>
<body>
Test: <input id="example" /> (try "C" or "E")
</body>
</html>
I implemented the MultiActionController with methodname resolver, the
method reuturns a LIST.
PROBLEM: nothing comes back for some reason.
Appreciate your help
thanks
