title: RadioButton ngmodel not working for boolean values
body: <p>I have two radio buttons in Sample with ngModel.</p>
  
  <pre><code>&lt;div id="container"&gt;
      &lt;input type="radio" id="radiobuttonstoerung1" label="Blinkend" name="stoerungBlinkend" [(ngModel)]="project.modelvalue"
            value="true"/&gt;
      &lt;input type="radio" id="radiobuttonstoerung2"  label="Dauersignal" name="stoerungBlinkend" [(ngModel)]="project.modelvalue"
    value="false"/&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>When I passed the boolean variable it is not working. </p>
  
  <pre><code>export class RadioButtonController implements OnInit {
      project = { modelvalue: true };
  }
  </code></pre>

  <p><em>Scenario</em> when I passed 'stoerungBlinkend' as true, RadioButton with value="true" should be checked. If I passed it as false, then RadioButton with value ="false" should be checked.</p>
  
  <p>I have found the workaround solution, but could anybody explain in detail why the above scenario is not working?</p>
