This is what Web Forms 2 says about the "change" event:

> In [DOM3EVENTS] and [HTML4], the change event is fired on a form control element when the control
> loses the input focus and its value has been modified since gaining focus.
>
> This specification changes these semantics to more accurately reflect the behaviour expected by Web
> authors. Specifically, for controls implemented with a non-editable stateful UI (e.g. select elements,
> checkboxes, or radio buttons as deployed in typical desktop Web browsers), the change event shall
> be fired when the selection is completed, even if the control does not lose focus. (For example, if a 
> date control has a button which shows a calendar, then the change event would fire when the
> calendar is closed after the user selected a date.)

It's not entirely clear if it means the "change" event to apply even to
controls that never take focus at all, but I gues that would make sense and
would match checkboxes and radio buttons.
