angularjs - typescript complains about call signature when testing $componentController -

i trying test angular 1.5 component, typescript throwing red in console.

(17,27): error ts2349: cannot invoke expression type lacks call signature. type 'icomponentoptions' has no compatible call signatures. phantomjs 2.1.1 (windows 8 0.0.0) component: recipecontainer should have defined component failed

am including files incorrectly? (i'm using webpack compile).

am missing type definition?

any appreciated, been scratching head hours now.

spec file:

import * angular 'angular'; import 'angular-mocks';  import { recipecontainer } './recipe-container.component'; import { recipes } '../recipe-store';  describe('component: recipecontainer', () => {     let $componentcontroller: ng.icomponentoptions;      beforeeach(angular.mock.module('app'));     beforeeach(angular.mock.inject((_$componentcontroller_: ng.icomponentoptions) => {         $componentcontroller = _$componentcontroller_;     }));      it('should have defined component', () => {         const bindings = { recipes };         const component = $componentcontroller('recipecontainer', null, bindings); //webstorm underlines line          expect(component).tobedefined();     }); }); 

component.ts:

class recipecontainercontroller implements ng.icomponentcontroller {     constructor(private $log: ng.ilogservice) {     }     $oninit() {         this.$log.info('inside oninit');     } }  export const recipecontainer: ng.icomponentoptions = {     bindings: {         recipes: '<'     },      controller: recipecontainercontroller,      template: '<div>hello</div>' }; 

$componentcontroller has icomponentcontrollerservice type. not icomponentoptions. if use wrong type on variable, can expect typescript type system complain.

it should be

beforeeach(angular.mock.inject((_$componentcontroller_: ng.icomponentcontrollerservice) => {   ...
