IE Error - Object doesn't support this property or method
===

I'm using jQuery and SimpleModal to create a submission form in a modal. For submitting the form, I'm using prototype.js

Following is my code:


    function testsubmit() {
     var $j = jQuery.noConflict();

     $('testForm').request({
       onCreate: function() {
         var $j = jQuery.noConflict();
         $j("#updateResult").html('Testing');
       },
       onComplete: function(){
         var $j = jQuery.noConflict();
         $j("#updateResult").html('It works!');
       }
     });

    }

This works fine on Firefox, Chrome, Opera and Safari but doesn't work in IE7, IE8, IE9. I've also tried adding

    <script type="text/javascript">var $j = jQuery.noConflict(); </script>

right after loading jQuery. That didn't help either.

Is there a workaround?
