Ember - nested recursive modules

I am working on an click and drop feature --- where on the page the module is used in a recursive way so it has a parent and children.

I have hit an issue where if the user started to select the children - and then selects the parent - I want to deselect the children. Although I am unsure how to store or monitor a change in the parent/child items selected to make global deselection.

So the user has selected the child of bacon3.. if they select the parent - it would need to deselect the children -- but I feel I am currently locked in the scope of the module
