Cannot read property '$setTouched' of undefined

[GabrielMSharp]

The line:
$scope.fc.$setTouched();
returns setTouched undefined when an item type of 'multiCheckbox' is changed.

This seems to be because 'fc' on the scope is undefined. I believe SC is the formcontrol, but can't see where this is set or unset.

I re-wrote that control to add a few extra pieces I needed and noticed that fc is now an array and I had to reference one of the objects in the array.
