If we want to call example method of:
"test1 DIV controller"
from:
"test2 DIV controller"
then we can write above method.

angular.Element(document.getelementByID('testDIV')).scope().example method name();

in test2DIVcontroller.

For Example : 

<DIV ID="test1DIV" ng-controller="test1DIV controller"></DIV>
<DIV ID="test2DIV" ng-controller="test2DIV controller"></DIV>

You can use a service to get the value set by one controller into another controller.

.service('someService', function () {
  this.language = null;
})

Controller

.controller('demoCtrl', function($scope, $rootScope, someService) {
    $scope.setLanguage = function(language) {
        $scope.language = language;
        someService.language = language;
        $rootScope.$broadcast('languageChanged');
    } 
});

In the other controller

.controller('someCtrl', function($scope, $rootScope, someService) {
    $rootScope.$on('languageChanged', function () {
        $scope.language = someService.language;
    }
});

You can share data between controllers with the help of either a service or you can use $emit() and $broadcast() functions.

There is a listener function in AngularJS $on() which will always be listening to the broadcast and emit events.

The syntax for the above function :

$scope.$emit(‘name1’,{}); //here you can send your data
$scope.$broadcast(‘name2’,{});
$scope.$on(‘name2’,function(event,args){
});

When using a service you can simply inject the service into your two controllers and share the data.

.service('someService', function () {
   var self=this;
   self.language = '';
});

.controller('firstCtrl', function($scope, someService) {
    $scope.setLanguage = function(language) {
    $scope.language = language;
    someService.language = language;
    } 
});

.controller('secondCtrl', function($scope, someService) {
    $scope.language = someService.language;
 });
