Angular - Directive with controllerAs, bindToController, and $scope.$watch
<p>I have a fairly straightforward AngularJS question to which I cannot seem to find an answer:</p>

<p>How would I go about using <code>$scope.$watch()</code> in a directive controller while also using the <code>controllerAs</code> and <code>bindToController</code> options? </p>

<p>Please let me know if you need any clarification on what I mean exactly. </p>
