title: ionic2 ion-list with a button both having (click) event
body: <p>What I am trying to achieve is when I click on the download button it should do somthing else and when clicking on the item it should open a new window</p>
  
  <pre><code>&lt;ion-list&gt;
      &lt;ion-item *ngFor="let reading_material of reading_materials" (click)="gotoReadingMaterial(reading_material)"&gt;
          {{reading_material.title}}
          &lt;ion-icon item-right name="download" (click)="downloadMaterial(reading_material)"&gt;&lt;/ion-icon&gt;
      &lt;/ion-item&gt;
  &lt;/ion-list&gt;
  </code></pre>
  
  <p>But when I click on the download button, both the events gets hit.
  Is there a way i can suppress the item event when i click on the download button ??</p>
