Accessing the same variable in a directive and controller in AngularJS

A few days ago, I was working with this type of structure in AngularJS:

I had a directive, contentTagButtons inside of an Angular controller, which was pretty basic.  I needed to be able to assign a value to a variable in the contentTagButtons directive, but still have access to it in formController. This is where directive scope comes in handy.

In my directive:


For my purposes when I set the scope attribute to false, the directive uses its parent scope. This means that $scope.someSharedVar my contentTagButtons directive  would be the same as $scope.someSharedVar in my formController controller.
