title: Framework7 v3 - How to trigger tab show
body: <p>I am using F7 v3 and using tabs, but how can I trigger tab show event?</p>
  
  <p>In the docs it says like this "tab:show" <a href="https://framework7.io/docs/tabs.html" rel="nofollow noreferrer">https://framework7.io/docs/tabs.html</a>
   and I try this but does not work</p>
  
  <pre><code>  $$('#latest').on('tab:show', function() {
      app.alert('latest is visible');
    });
  </code></pre>
