change() event problem in internet explorer

change() event problem in internet explorer

Hello , i'm running intro a problem with a change on a form , identified either by it's id or simply form . In firefox the changes made on any of the form elements are being evaluated but this doesn't happen in IE.
I'm using it this way
$('#compara').change(function()
{ //do stuff here like show some data in a div with .html() method etc .. );}
where #compara is the id of the form .
Here's a live example : http://reloadro.dyndns.org/rca/templates/sb/home.html
At the moment it's working because i'm adding the change event on each of the form elements instead on the whole form,luckily i have only 5-6 elements .
Can anyone enlighten me on why aren't the form changes detected by IE please ?
