Since a radio button group can have only one option checked, we'd 
want to clear the 'checked' attribute for every non-sausage field:

         if (el.get('value') == 'sausage')
         {
                 el.set('checked', true);
                 return true;
         }
         else
         {
                 el.set('checked', false);
                 return false;
         }

or, more concisely although perhaps not as readably:

         var bState = (el.get('value') == 'sausage');
         el.set('checked', bState);
         return bState;

Regards,
