element.click in directive unit test not assigning value to variables

I am testing the directive below that uses an isolated scope. I know the triggerHandler is working but for some reason I keep getting the error

Expected undefined to equal 'http://ift.tt/15PRIlY'.

Directive:

angular.module('pb.webSites.directives')
    .directive('pbOrganizationImagePicker', [ function () {

        return {
            restrict: "E",
            template: '<img data-ng-src="{{ imageSource }}" width="{{width}}" height="{{height}}" alt="Image Picker" class="img-rounded" />',
            scope: {
                fileId: '=pbFileId',
                defaultSrc: '@pbDefaultSrc',
                width: '@pbWidth',
                height: '@pbHeight'
            },
            controller: 'pbOrganizationImagePickerController',

            link: function (scope, element, attrs) {
                scope.$watch('defaultSrc', function (value) {
                    if (value !== undefined) {
                        scope.imageSource = value;
                    }
                });

                element.on('click', function () {
                    scope.pickImage().then(function (image) {
                        scope.imageSource = image.storageUrl;
                        scope.fileId = image.fileId;
                    }, function () {
                        console.log('Modal dismissed at: ' + new Date());
                    });
                });
            }
        };
    }]);

Tests:

describe('pbOrganizationImagePicker', function () {

    beforeEach(module('pb.webSites.controllers'));
    beforeEach(module('pb.webSites.directives'));
    beforeEach(module('ui.router'));
    beforeEach(module('ui.bootstrap'));

    var compile;
    var scope;
    var mockModal = {};
    var image;

    beforeEach(inject(function ($compile, $rootScope) {
        compile = $compile
        scope = $rootScope.$new();
    }));


    beforeEach(inject(function ($q, $injector) {

        $httpBackend = $injector.get('$httpBackend');
        $httpBackend.whenGET('/app/webSites/directives/OrganizationImagePicker.html').respond(200, '');

        scopeObject = {
            profileImageUrl: 'http://ift.tt/15PRIlY',
            profileImageId: 54634
        };

        scope.webSite = {
            profileImageId: 6436
        };

        scope.pickImage = function () {
            var defer = $q.defer();
            defer.resolve(scopeObject);
            return defer.promise;
        };

    }));

describe('element.click()', function () {

        beforeEach(function () {
            var html = angular.element('<pb-organization-image-picker data-pb-default-src="{{ webSite.profileImageUrl || \'/content/img/placeholder-lg.jpg\' }}" data-pb-file-id="webSite.profileImageId" data-pb-width="200"></pb-organization-image-picker>');
            element = compile(html)(scope);
            element.triggerHandler('click');
        });

        it('should assign value to scope variables', function () {
            scope.pickImage();
            scope.$digest();
            expect(scope.imageSource).toEqual(scopeObject.profileImageUrl);
            expect(scope.fileId).toEqual(scopeObject.profileImageId);
        });

    });

});
