Auto updating radio check

Question

Got this: http://jsfiddle.net/NdsF8/

Want it to be dynamic so when you click a new radio button, it changed the written value.

I'm sure this has been covered somewhere, but for the life of me cannot find it.

If you're magical enough, either PHP, JQuery, or then Javascript. Any will do but thats my preferred order :]

Answer 1

You have to add an event to do so :
