jQuery / Prototype bugs in IE

I use jQuery 1.2.1 and Prototype 1.5.1 libraries for some effects when deleting records from the database.  I have noticed it does not return the second callback response for all versions of IE - 5, 6 & 7 so i do not get my last effect occuring...

This is a bug or am I doing something wrong?  I have tested the script on a number of other browsers and it all works fine...so i guess it is an issue with Micro$lop browser - IE...

See my code below:
function removeRow(eid,mid) {
	var myAjax = new Ajax.Request("delete-email-alert.jsp?eid=" + eid, {
		method:'get',
		onSuccess: function(callback) {
			var object = new Ajax.Request("count-email-alerts.jsp?mid=" + mid, {
				method:'get',
				onSuccess: function(callback) {
					if(callback.responseText == 0) {
						$("#"+eid).fadeOut("slow", function() {
							$(this).html("<div class=\"col-empty\">All email alerts have now been deleted!</div>").fadeIn("slow");
						});
					} else {
						$("#"+eid).fadeOut("slow").slideUp();
					}
				}
			});
		}
	});
}

It is because of IE browser caching all responses from XMLHTTPRequest:

referf this place, it mentions the solution for this:

This issue can occurr with other browsers as well.  I use a Math.random() or Date() to make the urls' unique:

"delete-email-alert.jsp?eid=" + eid + "&cache=" + Math.random()
