Hi Sander,

Hope you are doing good.

Thank you for the implementation, removing usage of scope does make a lot 
of sense along with wrapping respective directives into a parent directive 
to handle events.

With this implementation the child element's viewValue gets clear on check 
event not on uncheck. However, by using ng-show we can accomplish it. 

The reason behind it could be the element is not rendered on to the screen 
with false condition, please correct me if I am wrong.

Is there any way we can use ng-if too, and clear the child elements value 
on uncheck event?

I have created plunker based on your plunker - link

Thank you,
Anurag.
