title: Ionic Keyboard close not fired
body: <p>I'm trying to close the keyboard when the user do scroll on the app. This is the code:</p>
  
  <p>.html</p>
  
  <pre><code>&lt;ion-content class="maincontent" (ionScrollStart)="scrollStart()"&gt;
    &lt;router-outlet&gt;&lt;/router-outlet&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>.ts</p>
  
  <pre><code>scrollStart() {
    Keyboard.close();
  }
  </code></pre>
  
  <p>The event <code>ionScrollStart</code> is working fine, and I have added the correct dependencies to make the Keyboard works. Any ideas?</p>
