Ionic iframe

How can I make the iframe reload when I re-enter the page using the tab menu:

home.html

<ion-content padding>
<iframe  src="http://page.com/categories" frameborder=0 style="width: 100%; height: 100vh;"></iframe>
</ion-content>

tabs.ts

<ion-tabs>
  <ion-tab [root]="tab1Root" tabTitle="Eventos" tabIcon="home" ></ion-tab>
  <ion-tab [root]="tab2Root" tabTitle="Crear Evento" tabIcon="information-circle"></ion-tab>
  <ion-tab [root]="tab3Root" tabTitle="Contacto" tabIcon="contacts"></ion-tab>
</ion-tabs>
