I'm trying to create a button-based approach to radio buttons within SilverStripe 3.0 and am having trouble hooking into the CMS jQuery hooks.

I have looked at the documentation on the matter (http://doc.silverstripe.org/framework/en/topics/javascript/) but am getting javascript errors on:

 Behaviour.register({ ...

Basically I need to detect when the current page is fully loaded (after saving, publishing, deleting, loading new page, etc) so I can use jQuery and apply the appropriate styles and classes to the label elements (see screenshot - these are radio buttons).

How do I (using jQuery) listen for the PageLoaded hooks as discussed in the documentation (http://doc.silverstripe.org/framework/en/topics/javascript/)?

I'm having the same problem, I'm trying to load a javascript function after the page is loaded.

I get a Type Error: Object #<HTMLFormElement> has no method 'observeMethod'.

Any idea how this could be fixed?
