i'm testing controller containing 

$document.on('click', $scope.$apply.bind($scope, $scope.deactivate));

when test controller using jasmine & karma 

'use strict';  describe('controllers: arrayctrl', function() {     var scope;      beforeeach(module('ironridge'));      beforeeach(inject(function($controller,$rootscope) {         scope = $rootscope.$new();             $controller('arrayctrl', {                 $scope: scope             });           }));      it('test section ', inject(function($controller) {         expect(scope.pannels.length).tobe(0);     }));  });

i following error :

phantomjs 1.9.8 (linux 0.0.0) controllers: arrayctrl should located in quote section failed typeerror: 'undefined' not function (evaluating '$scope.$apply.bind($scope, $scope.deactivate)') undefined @ /home/hpro/ironridge/src/app/components/array/array.controller.js:183 @ invoke (/home/hpro/ironridge/bower_components/angular/angular.js:4219) @ instantiate (/home/hpro/ironridge/bower_components/angular/angular.js:4227) @ /home/hpro/ironridge/bower_components/angular/angular.js:8533 @ /home/hpro/ironridge/bower_components/angular-mocks/angular-mocks.js:1878 @ /home/hpro/ironridge/src/app/components/array/array.controller.spec.js:11 @ invoke (/home/hpro/ironridge/bower_components/angular/angular.js:4219) @ workfn (/home/hpro/ironridge/bower_components/angular-mocks/angular-mocks.js:2437) typeerror: 'undefined' not object (evaluating 'scope.pannels.length') undefined @ /home/hpro/ironridge/src/app/components/array/array.controller.spec.js:17 @ invoke (/home/hpro/ironridge/bower_components/angular/angular.js:4219) @ workfn (/home/hpro/ironridge/bower_components/angular-mocks/angular-mocks.js:2437)

help please 

$document.on('click', $scope.$apply.bind($scope, $scope.deactivate));

i don't think above code works. guess trying apply scope. can do

    $(document).on('click', function(){         if(!$scope.$$phase){             $scope.$apply();         }         $scope.deactivate();    });

coming test case, bind function in angularjs used as

angular.bind(self, fn, args)

according documentation. in jquery, bind used attach handler event elements. in case $scope.$apply.bind not work. reason test case throwing error.
