Sharing Data Between Controllers, Angularjs 1.3 version -

i working on this jsfiddle, in angularjs 1.2.17
when try same script angularjs 1.3.14 gives error, see console.

finally when try this fiddle again 1.3.14 version:

<div ng-app='app'>     <div ng-controller="firstctrl">         <input type="text" ng-model="data.msg" />          <h1>{{data.msg}}</h1>      </div>     <div ng-controller="secondctrl">         <input type="text" ng-model="data.msg" />          <h1>{{data.msg}}</h1>      </div> </div>  var app = angular.module('app', []);  app.factory('data', function () {     return {         msg: "i data service"     }; }); app.controller('firstctrl', ['$scope', function($scope, data){     $scope.data = data; }]); app.controller('secondctrl', ['$scope', function($scope, data){     $scope.data = data; }]); 

i not make work: not give error data.msg not update in both controller.
