In this code, the controller is being supplied an injected scope and rootScope, so why does it fail on the last line with:

ReferenceError: $rootscope is not defined

```
angular.module("myEntity").controller('productsCtrl', [
    '$scope', 'MyAction', '$rootScope', function ($scope, MyAction, $rootScope) {
        $scope.propertyValue = something;
        $scope.canDoSomething = $rootscope.myRootScopeProperty = 1;
        .... 

```
