Angularjs Resource - how to get the response from .$save

Question

I'm saving some data which I get a response from my API correctly. After that, I'm trying to use that information once my .$save function ends. Here's my code:

auxPostulation = new Postulation($scope.postulation);
                        auxPostulation.$save(null, function(response){
                   //I get the response and the id value without trouble.
                            $scope.postulation_id = response.id;
                        },function(error){
                            console.log('erro');
                        });

I wanna use that response outside that call but I cannot reach it. Always getting '$scope.postulation_id = undefined'.

How this function behave?

Thank you in advanced.

Declare the variable $scope.postulation_id outside the Postulation block and then assign it inside the block. Note that you might still get undefined in case the callback has not completed when you call for $scope.postulation_id . You might need to lay your code properly to take care of that issue, using $timeout or another callback in some cases.
