title: Angular 2 radio button events
body: <p>What are those events called in Angular 2 when radio button is selected or unselected.</p>
  
  <p>Something like </p>
  
  <pre><code>&lt;input type="radio" (select)="selected()" (unselect)="unselected()" /&gt;
  </code></pre>
  
  <p>So when I click one radio button in a group, it will fire <code>selected()</code> for the new selection and <code>unselected()</code> for the previous selection.</p>
