How to call controller method from the app.js in angular

I want to call the controller method [getFacility()] from the app.js file. but when I used the below code segment I got the error like

Error: [$injector:unpr] Unknown provider:

here my controller files and service files

app.js

...
...     
.state('facilityHome.editFacility', 
{
   url: '/editFacility/:facilityId',
   templateUrl: '/views/facility/newFacility.html',
   controller: 
        function($scope, $stateParams, facilityController) {
                facilityController.getFacility($stateParams.facilityId);
         }
}

....
...

facilityControlelr.js

app.controller('facilityController',
['$scope', '$rootScope','$location','$filter', 'facilityService',
    function ($scope, $rootScope,$location,$filter, facilityService){

        /* Assign Object */
        var facilityScope = this;

        /* Initialize DTO Object */
        facilityScope.facilityDTO={
            id:null,
            version:null,
            facilityName:"",
            description:""
        };


        /* Initialize Object Array */
        facilityScope.facilityList = [];


        facilityScope.getFacility=function(id){
            facilityService.fetchFacility(id)
                .then(
                function(successRespond) {
                    $scope.facilityDTO = successRespond;
                },
                function(errResponse){
                    console.error('Error while fetching');
                    console.error(errResponse);
                }
            );

        };

    }
]);

Here What I got in my console.

To inject a controller into another controller, use the $controller service.

.state('facilityHome.editFacility', 
{
   url: '/editFacility/:facilityId',
   templateUrl: '/views/facility/newFacility.html',
   controller: 
       function($scope, $stateParams, $controller) {
           var facCtrl = $controller("facilityController", {'$scope': $scope});
           facCtrl.getFacility($stateParams.facilityId);
       }
}

Because the facilityController manipuates $scope, $scope needs to be injected as a local.

For more information,see AngularJS $controller Service API Reference.
