Google Calendar iframe not updating with ion-refresh

Ionic Framework ionic-v3
1

I have the following html in my home.html page :

  <div class="googleCalendar">
    <iframe src="https://calendar.google.com/calendar/embed?showDate=0&amp;showPrint=0&amp;showCalendars=0&amp;height=600&amp;wkst=2&amp;hl=ro&amp;bgcolor=%233366ff&amp;src=catalintium%40gmail.com&amp;color=%231B887A&amp;ctz=Europe%2FBucharest?nocache"
      style="border-width:0" width="400" height="600" frameborder="0" scrolling="no"></iframe>
  </div>

And this inside my home.ts Homepage class :

doRefresh(refresher) {
console.log(‘Begin async operation’, refresher);

setTimeout(() => {
  console.log('Async operation has ended');
  refresher.complete();
}, 2000);

}

The calendar itself is showing,but everytime I add events in Google calendar, they won’t appear in my calendar no matter how much i refresh the page. Thanks for helping.
