@After

export declare let After: (value: string) => Function;

@After decorator is used to bind route action name to method

@Controller({
   name: "home"
})
export class HomeController {


  @Action("index")
  processIndexAction() {
      return this.viewService.compileTemplate("home/index", {data: "HTML STRUCTURE"});
  }

  @After("index")
  afterIndexAction(@Chain data) {
     return this.service.modifyCompiledHtml(data);
  }

}

This will match route home/index route or moduleName/home/index.
