title: Ionic 2 - Access ngModel in controller
body: <p>I'd like to access my ngModel in a controller, for some reason I can't find out how to do it. I've got a <code>radio-group</code> (which does not belong to a form, but just to a splashscreen where users can personalize the application.</p>
  
  <p><strong>My html:</strong></p>
  
  <pre><code>&lt;ion-list radio-group [(ngModel)]="language"&gt;
      &lt;ion-list-header style="word-break: normal;"&gt;
          {{ languageText }}
      &lt;/ion-list-header&gt;
  
      &lt;ion-item&gt;
          &lt;ion-label&gt;Nederlands&lt;/ion-label&gt;
          &lt;ion-radio value="nl"&gt;&lt;/ion-radio&gt;
      &lt;/ion-item&gt;
  
      &lt;ion-item&gt;
          &lt;ion-label&gt;English&lt;/ion-label&gt;
          &lt;ion-radio value="eng"&gt;&lt;/ion-radio&gt;
      &lt;/ion-item&gt;
  
      &lt;ion-item&gt;
          &lt;ion-label&gt;Deutsch&lt;/ion-label&gt;
          &lt;ion-radio value="du"&gt;&lt;/ion-radio&gt;
      &lt;/ion-item&gt;
  &lt;/ion-list&gt;

  <p><strong>I want to access the <code>ngModel: language</code> in my controller:</strong></p>
