Re: radio button observe field only triggers once

If I remember correctly, I think you'll need an id on each radio
button and need to observe each radio button individually.  The
'grouping' of the radio buttons into a single field value that's
posted back does not replace the fact that it's actually a collection
of individual html elements on the form.
