angularjs - How can we watch expressions inside a controller in angular 1.4 using angular-new-router

Question

Since we cannot inject $scope inside controllers in Angular 1.4+, how can we watch expressions the way we used to do with $scope.$watch?

An attempt to inject $scope can be seen here ("Could not instantiate controller" error), and tutorials tells us that:

Angular wont be able to instantiate the controller if we pass $scope in it. It defines its observable properties on this. (source)

I have just found out that there is a bug on ngNewRouter causing this problem. It has been fixed, but haven't been released yet.

To workaround it, try this:

$ git clone git@github.com:angular/router.git
$ cd router
$ npm install
$ gulp angularify

after that, copy the dist files to your project
