In the latest revision (I changed the implementation of radio buttons),
something like this should work :

| form |
form := e form.
model answers do: [:each |
        form radioButton
                group: 'answers';
                action: [self whatever: each].
        form text: each; break]

About the submit on change, there are two possibilities right now:

1. use onChange: 'submit()', but it won't use an AJAX request
2. use onChange:
'Iliad.evaluateFormAction(jQuery(this).closest("form"))' 

I know, the latest is tricky...

Cheers!
