Three rows of radio buttons with two exclusivity

I am a recent covert to Ionic from JQM - one thing I am trying to fathom out how to produce a grid with two-way exclusivity. I have sussed it in JQM but transitioning over seems like a whole new ball game.

I have attached a link to demonstrate what I am trying to achieve with a ionic interface - []

Thanks in advance.

Do you already have an app with the needed checkboxes setup correctly? If so, you should post this code here so someone can take a shot at it.
