Look at the generated HTML in a browser. In order for the label to affect the radio button, one of two things must be true:

1. Either the label's "for" attribute exactly matches the radio button's "id" attribute, or
2. The label wraps around the button and does not have a "for" attribute.

Sometimes you have to get out and push a little with radio buttons, although looking at it briefly, you appear to be doing the right things by having the same name input into both the label and the radio.
