$location.path("/abc") not working in particular functions

I have two functions defined as example. First one is

   $scope.redir = function () {
   $location.path('/abc');
  };

and it redirects fine, but next snippet doesn't work for some reason

  $scope.signup = function() {
  var user = {...}
  return $http.post('/auth/signup', user);
  $location.path("/abc");
  console.log($location.path());
  };

It does post part very well, user is added to a db correctly, but redirect doesn't follow. I've tried using $rootScope as adviced in few questions, but result is the same - button with signup() assigned does http.post and stops at "pushed" state with no redirect following. Here's what I pass to Ctrl by the way

function($scope, $location, $http)
