Cannot Select Radio Button (Boxes) When Inserted Dynamically

Cannot Select Radio Button (Boxes) When Inserted Dynamically

Hello, 
I am using jQuery UI and the Tabs. When I click on a tab I also am updating another div with a new title and some radio buttons, BUT when I do this, the radio buttons are no longer functioning.

I had a fiddle to demonstrate:

When the page loads I insert the first lot of title information from a hidden div and when the second tab is pressed another piece of hidden div info loads.

There is one radio button "selected" so it remains highlighted but I cannot get the others to respond like normal jquery UI radio buttons??

Is it because the title and buttons are hidden to begin with? Maybe? how would one fix that?

Or is this just poor in terms of implementation? I am new to jquery UI and welcome any feedback.

Thankyou
