title: How to submit form with method post in angular 2 using formgroup
body: <p>I am trying to make a post request in angular, but as i found out, I can not do that, if I use <code>[formGroup]</code>, because submit button does nothing. My code looks like that</p>
  
  <pre><code>&lt;form [formGroup]="formGroup" action="https://someUrl.com" method="post"&gt;
      &lt;input type="text" name="lang" id="lang" value="en" formControlName = "lang" &gt;
      &lt;input type="submit" &gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>If I remove <code>formGroup</code> module, it works fine. Is there a bug, a submit override or something? </p>
