title: There is no ng-init for Angular2
body: <p>As we all know there is no ng-init or something for Angular2. So if we try do do something like:</p>
  
  <pre><code>&lt;div #rr="2+2"&gt;
   {{rr}}
  &lt;/div&gt;
  </code></pre>
  
  <p>We will get runtime error:</p>
  
  <p><code>Error: There is no directive with "exportAs" set to "2+2"</code></p>
  
  <p>I was watching one of the Angular2 dev videos on <a href="https://youtu.be/bVI5gGTEQ_U?t=1227" rel="noreferrer">youtube</a> and saw exactly the same construction meant to work.
  Here is the screenshot:

  <p>How is this assignment to user template variable possible?</p>
