Radio button is still a button. It looks like you did the popup mechanically, from someone's code sample, without understanding. Now, it's the time to take you old code and really understand how it works, that will solve your new problem. Radio button will work exactly the same way. You may only need to know the checked status of the radio button. See, for example:
