问题 I am developing hybrid app based on angular.js using cordova. I have faced the problem not accessing to angular variables $ (like $rootScope) after executing the followings. cordova and angular.js finished to be initialized as soon as this hybrid app is launched.

But suppose I go from state A to B to C and back to B, the alert statement does NOT go off. However, if

问题 I know this issue has been asked several times in stackoverflow, but I couldn't find a proper answer. What I need to achieve is to be able to initiate some asynchronous call in one controller and when the result returns update the $scope in some other controller. I understand that I should use a shared service that actually does the $http stuff, but I can't manage to update the other controller scope.

For eg: If I Click a "Signout" button to redirect to "signin" page, then all the $scope or $rootScope values in the session should be cleared.
