Firebase authentication on App initilisation - firebase

Question

This is works:
console.log('User ID: ' + user.id + ', Provider: ' + user.provider);
but this one is not:
$scope.authenticated.currentUser = user.id;
My goal here is to take to take some of the authentication variables (Email+UserID) and then use them to access a profile node ON firebase. On initialization I want the username, email, and a few other things I need for the app.
crossfitApp.controller('globalIdCtrl', ["$scope",'defautProfileData','$q', function ($scope,defautProfileData,$q) {
var dataRef = new Firebase("https://glowing-fire-5401.firebaseIO.com");
$scope.authenticated={
currentUser: $scope.authemail,
emailAddress: "",
settings: "",
};
var chatRef = new Firebase('https://<YOUR-FIREBASE>.firebaseio.com');
var auth = new FirebaseSimpleLogin(chatRef, function(error, user) {
if (error) {
// an error occurred while attempting login
switch(error.code) {
case 'INVALID_EMAIL':
case 'INVALID_PASSWORD':
default:
}
} else if (user) {
// user authenticated with Firebase
console.log('User ID: ' + user.id + ', Provider: ' + user.provider);
$scope.authenticated.currentUser = user.id ;//
} else {
// user is logged out
}
});
}]); //GlobaldCtrl

Most likely, you're running into a problem with Angular's HTML Compiler.
Whenever you use an event like ng-click/ng-submit/etc, Angular fires $scope.$apply(), which checks for any changes to your $scope variables and applies them to the DOM.
Since FirebaseSimpleLogin is not part of Angular's purview, it has no idea that when the callback is fired, you've updated $scope.authenticated.currentUser. This would also explain why it works when you call auth.login(), since you're probably invoking that via an ng-click event somewhere, which would fire a digest check and discover the changes.
If this is indeed the case, you can correct this issue by alerting Angular that it needs to run $apply by using $timeout:
crossfitApp.controller('globalIdCtrl', ["$scope",'defautProfileData','$q', '$timeout', function ($scope,defautProfileData,$q, $timeout) {
/* ... */
var auth = new FirebaseSimpleLogin(chatRef, function(error, user) {
if (error) {
/* ... */
} else if (user) {
$timeout(function() {
$scope.authenticated.currentUser = user.id ;//
});
} else {
// user is logged out
}
});
