[AngularJS] How do I make scope destroy event to wait for the promise to resolve ?

[Rahul Tokase]

Hi 

I have written a directive in which on destroy event i need to call some 
AJAX request and I want my destroy event to wait for the AJAX call to 
finished.

Here is my code.

scope.$on('$destroy', function() {                   
                     
                        callmethodAsync("").always(function() {
                            // Do some cleanup or logging
                            console.log('inside remember');
                        });
                       
                });

Here i want my destroy method to wait for asyn method execution. How I can 
achieved that.
