angularjs - Call Angular directive controller method from another controller -

i have directive associated 1 controller , functions in controller defined

   myformcontroller.prototype.addnewrow = function addnewrow() {              //adding row code }; 

i want call method controller, possible ways?

i ve user service , moved code service shared across controllers, service code dom manipulation, , guess next question can use $compile in service test case

service or factory used share data between controller.so best define function in service , factory.

demo:

(function() {     angular.module('app', [])         .service('svc', function() {             var svc = {};              svc.method = function() {                 alert(1);             }              return svc;         })         .controller('ctrl', [             '$scope', 'svc', function($scope, svc) {                 svc.method();             }         ]); })();
