title: The method "date" that you're trying to access does not exist in the class declaration
body: <p>It's kind of silly question but here's one:</p>
  
  <blockquote>
    <p>./SPA/app/foo/foo-list/foo-list.component.ts
    (Emitted value instead of an instance of Error) [19, 56]: The method "date" that you're trying to access does not exist in the class declaration.</p>
  </blockquote>
  
  <p>I'm using angular with date pipe which is integrated at angular itself. </p>
  
  <p><code>{{ item?.created | date:'dd' }}</code></p>
  
  <p>And tslint produce that annoying warning. I use webpack with tslint-loader.</p>
  
  <p>Well, any advice? :)</p>
