angularjs share data config between controllers

Question

I\'m wondering what could be a good way to share directive between controller. I\'ve got ie two directives to use in different controller with different configuration the fi

Answer 1

obvious but brilliant solution (may be)

(function(window, angular, undefined) {
                'use strict';
                angular.module('ctrl.parent', [])
                    .run(function ($rootScope) {
                        $rootScope.test = 'My test'   
                        $rootScope.myTest = function(){
                            alert('It works');
                        }
                });
            })(window, angular);
            angular.module('app',['ctrl.parent'])
                .controller('ChildCtrl', function($scope){

            });

It's easy and clean and don't see any drawback(it's not global)

UPDATE

'use strict';
                (function(window, angular, undefined) {
                    'use strict';
                    angular.module('ctrl.parent', [])
                        .controller('ParentController',function (scope) {
                            scope.vocalization = '';
                            scope.vocalize = function () {
                                console.log(scope.vocalization);
                            };
                    });
                })(window, angular);
                angular.module('app',['ctrl.parent'])
                    .controller('ChildCtrl', function($scope,$controller){
                    angular.extend($scope, new $controller('ParentController', {scope:$scope}));
$scope.vocalization = 'CIP CIP';
                });

just a little neater and it works CIP CIP :)
