[jQuery] Attaching an event to a non-existing element?

[Octavian Râşniţă]

Hi,

I want to set an event handler which is executed after clicking on an 
element from a combo box, but that combo box doesn't exist when the page is 
created. It is generated by an AJAX request.

I've tried to set an event using:

$(document).ready(function(){
$('#term2').onchange(function(){
  window.location = http://www.google.com/;
}
}

But this code is not executed, even though I tried to change the selection 
using the keyboard.

Is there a way of setting this event handler if the html element is created 
later by an AJAX request?

Thanks.

Octavian
