title: Ionic tabs re-init component
body: <p>I am using <code>ion-tabs</code> and <code>ion-tab</code> components for <code>Ionic 3</code>. Currently, when user switches between tabs the component in the tab <code>&lt;ion-tab [root]="SomeComponent"&gt;&lt;/ion-tab&gt;</code> is only initialized when the user switches to it first time. After that ,there is no more call of the <code>ionViewDidLoad</code> or <code>ngOnInit</code>. The question is: Is it possible to destroy the component on tab change and then initialize it again later?</p>
