[Firebase + Angular] $authWithOAuthPopup not updating HTML UI

Sorry for reposting this issue but I was unable to reply to post I found to
ask for a fix.

I have a login controller which actually does login the user just fine. but
requires a page refresh to show tht the use is logged in... logging out
updates the UI just fine... loggin in does not.

Here is the controller I am using... this is one of many iterations so far
to get his working. ANY help is appreciated

.controller('LoginCtrl', function($scope, $timeout, $ionicModal, Auth) {

    // Auth
      $scope.auth = Auth;

   $scope.user = $scope.auth.$getAuth();

    $scope.login = function(provider) {

        $scope.auth.$authWithOAuthPopup(provider, function(error, authData) {

            $scope.$apply(function() {

                $scope.user = authData.auth.$getAuth();

            });

        });

    };

    $scope.logout = function() {

        $scope.auth.$unauth();

        $scope.user = $scope.auth.$getAuth();

    };

})
