AngularJs unit test: "Unsatisfied requests: DELETE" - angularjs

Question

Getting "Unsatisfied requests: DELETE" for my controller test. below are the code for my service, controller and test. tests are written using jasmine-karma and angular-mock. Thanks in advance.
service:
function deleteAsset(assetId) {
return $http.delete(baseUrl + '/delete/' + assetId).then(assetDeleted);
function assetDeleted(response) {
return response.data;
}
}
Controller:
(function () {
'use strict';
angular.module('tbApp').controller('assetEditCtrl', assetEditCtrl);
assetEditCtrl.inject = ['$routeParams', 'Campaign', 'User', '$location', 'Asset', '$window', '$scope', '$compile', 'ImageLibrary', 'Lists'];
function assetEditCtrl($routeParams, Asset, $window, $scope, $compile) {
function deleteAsset(assetId,assetType,assetName, el) {
//confirmation popup
CB.setProceedBoxCode("Are you sure you want to delete "+assetType+" "+assetName+"?", el, {OK: "Yes", CANCEL: "No", width: "400", title: "", callback: function (r, ele) {
if (r == true) {
Asset.deleteAsset(assetId).then(assetDeleted);
}
}});
function assetDeleted(data) {
backTodashbiard();
}
} } });
Test:
describe('assetEditCtrl', function() {
var scope, httpBackend, http, controller, vm, createController, assetId, el, assetType, assetName, compile;
var baseUrl = './webresources/assets';
beforeEach(module("tbApp"));
beforeEach(inject(function($rootScope, $httpBackend, $controller, $http, $compile) {
httpBackend = $httpBackend;
compile = $compile
scope = $rootScope.$new();
controller = $controller;
assetId= "EML1000006003";
campaignId="CMP1000004385";
createController = function() {
var controller = $controller('assetEditCtrl', {
'$scope': scope
});
return controller;
};
}));
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
})
it('should be able to delete an asset', function(){
vm=createController();
assetType="email";
assetName="Untitled";
httpBackend.expectDELETE(baseUrl+'/delete/'+assetId).respond({});
vm.deleteAsset(assetId,assetType,assetName, el);
httpBackend.flush();
});});
Output:
