Nested radio inputs destroys data-binding

Hey ionic team,

i have a problem with nested radio inputs.

i have a list of items.
One item has a label and an array of values.
The values are shown as radio inputs.

The model for each radio input and every item is the same!
So i have a list of items with a sublist of radio buttons.
With the same ngModel on the radio buttons.

And at this point ionic breaks the ng-model handling i think.
Sometimes my changes are not recognized (only of the first value of the item).

If i remove all ionic classes, everything works fine.

Greets, bengtler.

Can you post of demo of this?

After some clicking around two elements are selected.
