Can't get Ajax to work

There must be an easy solution to this problem, but I'm unable to get Ajax to work.

In my XHTML file I have something like:

Then in my bean I have this:

What is supposed to happen is when I check the checkbox, the contents of the <h:panelGrid> tagged with the id="objectirradiated" are supposed to be rendered, and when I uncheck the checkbox , they are not rendered. Instead nothing happens, but the page is displayed correctly if I refresh the browser. The whole idea of using Ajax is to refresh part of a page without having to reload it, so something is obviously wrong.

I put in a printout to the server in the action method at the end of the Java code, and indeed the status of the booloean is updated when status of the checkbox is changed.

This must be a simple problem to solve, but obviously something is going wrong, so some help would be very much appreciated.

The chronology of processing on checkboxes is extremely bizarre, even when not using JSF. Try keying on the "change" event instead of "click".

An IDE is no substitute for an Intelligent Developer.
I agree. Here's the link:
