title: Angular2 - Radio Button Binding
body: <p>I want to use radio button in a form using Angular 2 </p>
  
  <pre><code>Options : &lt;br/&gt;
  
  1 : &lt;input name="options" ng-control="options" type="radio" value="1"  [(ng-model)]="model.options" &gt;&lt;br/&gt;
  
  2 : &lt;input name="options" ng-control="options" type="radio" value="2" [(ng-model)]="model.options" &gt;&lt;br/&gt;
  </code></pre>
  
  <p>model.options initial value is 1</p>
  
  <p>when the page is loaded the first radio button isn't checked and the modifications aren't binded to the model </p>
  
  <p>Any Idea ? </p>
