javascript - How do I get an instance of a controller that was created by AngularJS? -

i have app based on angular initialize this:

myapp.init = (function () {   'use strict';    var angularapp = angular.module('myapp', [])     .directive('homeiterationdirective', function () {       return function (scope, element, attrs) {         var istopcard = scope.$last ? true : false;         cards.initsingleswipe(element.get(0), function (event) {           // want call indexpagecontroller.onswiped(event) here!         }, istopcard);       };     })     .directive('homedirective', function () {       return function (scope, element, attrs) {         cards.initpanel(element, function (event) {             // want call indexpagecontroller.onbuttonpressed(event) here!         });       };     });    angularapp.factory('ajaxservice', myapp.services.ajaxservice);   angularapp.controller('indexpagecontroller', ['$scope', '$http', '$sce', 'ajaxservice', myapp.pages.indexpagecontroller]);  }()); 

my controller looks this:

myapp.pages.indexpagecontroller = function ($scope, $http, $sce, myservice) {   'use strict';    var somevalue = {};    this.onswiped = function (event) {     dosomethingwith(event, somevalue);   };    this.onbuttonpressed = function (event) {     dosomethingwith(event, somevalue);     };  }; 

in 2 directives homeiterationdirective , homedirective have 2 callbacks cards.initsingleswipe , cards.initpanel. within these callbacks want call public methods of controller don't have instance available angular created indexpagecontroller. how can achieve this?

use (inject) service (and not controller) if want "to call public method" place, possibly controller.

angularapp.controller('mycontroller', function ($scope, indexpageservice) {     indexpageservice.blah(); })); 

controller intended receive , modify $scope (adding methods, variables..etc). $scope can used inside template (html) use controller itself.
