title: Using Pipes within ngModel on INPUT Elements in Angular
body: <p>I've an HTML INPUT field.</p>
  
  <pre><code>&lt;input 
      [(ngModel)]="item.value" 
      name="inputField" 
      type="text" 
  /&gt;
  </code></pre>
  
  <p>and I want to format its value and use an existing pipe:</p>
  
  <pre><code>.... 
  [(ngModel)]="item.value | useMyPipeToFormatThatValue" 
  ....
  </code></pre>
  
  <p>and get the error message:</p>
  
  <blockquote>
    <p>Cannot have a pipe in an action expression</p>
  </blockquote>
  
  <p>How can I use pipes in this context?   </p>
