Refresh parent Content out of child View
<p>is there a simple way, where I can tell the Parent View to refresh it's content?</p>

<p><a href="https://i.stack.imgur.com/1cxMf.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1cxMf.gif" alt="Filter Video"></a></p>

<p>In this case I'm changing the sort Model and would like to query my http Request with this new Model status. </p>

<pre><code>import {Component} from '@angular/core';
import {LoadingController,NavController,PopoverController,ViewController} from 'ionic-angular';
import {Http} from '@angular/http';
import 'rxjs/add/operator/map';
@Component({
template: `
&lt;ion-list radio-group [(ngModel)]="suchService.sort" class="popover-page"&gt;
  &lt;ion-item&gt;
    &lt;ion-label&gt;Entfernung aufsteigend&lt;/ion-label&gt;
    &lt;ion-radio (click)="sortchange()"value=""&gt;&lt;/ion-radio&gt;
  &lt;/ion-item&gt;
  &lt;ion-item&gt;
    &lt;ion-label&gt;Neueste zuerst&lt;/ion-label&gt;
    &lt;ion-radio (click)="sortchange()"value="9"&gt;&lt;/ion-radio&gt;
  &lt;/ion-item&gt;
  &lt;ion-item&gt;
    &lt;ion-label&gt;Preis aufsteigend&lt;/ion-label&gt;
    &lt;ion-radio (click)="sortchange()"value="1"&gt;&lt;/ion-radio&gt;
  &lt;/ion-item&gt;
&lt;/ion-list&gt;
`
})
class PopoverPage {

constructor(private suchService: SuchService, private viewController: ViewController) {

}
sortchange(){
  console.log("HALLO?"); &lt;-- CALL FUNCTION OF ERGEBNISSE
  this.viewController.dismiss();
}
}
export class Ergebnisse {
.....
getResults(){...}
....
}
</code></pre>

<p>I can't import the Ergebnisse class into my Popoverpage... Even if I use another .ts File for the Popoverpage...</p>
