Determining if checkbox is checked in Ionic 2
<p>How can I determine if a ion-checkbox is checked in Ionic 2.</p>

<pre><code>   &lt;ion-item *ngFor="let a of q.Answers"&gt;
      &lt;ion-label&gt;{{a.AnswerDescription}}&lt;/ion-label&gt;
      &lt;ion-checkbox (click)="addValue($event)"&gt;&lt;/ion-checkbox&gt;
   &lt;/ion-item&gt;
</code></pre>

<p>the following return <code>undefined</code></p>

<pre><code> addValue(e): void {
     var isChecked = e.currentTarget.checked;
     console.log(isChecked);//undefined

 }
</code></pre>
