title: Angular 2: CheckBox/Radio select deselect operation
body: <p>I have a list of ages over which i iterate and create the list of radio inputs. Then, I select one of those and want to deselect it on a click of a button clear. How can it be achieved on angular2 using typescript.</p>
  
  <pre><code>&lt;span *ngFor="let ageItem of ageList;"&gt;
      &lt;input type="radio" name="age" value="{{ageItem}}"
             (click)="filter($event.target.value)"&gt;
          &lt;span&gt;{{ageItem}} years&lt;/span&gt;&lt;br&gt;
      &lt;/span&gt;
  &lt;button md-button="" (click)="clearFilter()"&gt;Clear&lt;/button&gt;
  </code></pre>
  
  <p>P.S: the list contains 100 elements, So there will be 100 checkboxes/radio inputs. Please suggest accordingly.</p>
