You are directly assigning object to other object, so that will cause change in any of the object will update other object value. Use angular.copy instead of assigning object directly, that will create a new clone copy of that object will returned.

 var test=angular.copy($scope.name);

Why do the console.logs appear empty, even though they're executed before the while loop? Just wondering since this seems like really weird behaviour.
