Caching stops code execution?

[lbeckman]

Hopefully I am posting this in the correct place this time, my apologies if not.

Anyways, I have some user controls which I want to use for fragment caching.

These controls contain a bunch of imagebutton controls which are supposed to call a method in the code associated with each user control which handles what the button is supposed to do and all.

These buttons work correctly when I do not cache the user control,
but when I add:

<%@ OutputCache Duration="60" VaryByParam="None" %>

to the user control page, caching it, clicking on the buttons seems to do nothing aside from refreshing the page.

Any insight would be of great use, thanks.
