Q:

Refresh parent Content out of child View

is there a simple way, where I can tell the Parent View to refresh it's content?

In this case I'm changing the sort Model and would like to query my http Request with this new Model status. 
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: `
<ion-list radio-group [(ngModel)]="suchService.sort" class="popover-page">
  <ion-item>
    <ion-label>Entfernung aufsteigend</ion-label>
    <ion-radio (click)="sortchange()"value=""></ion-radio>
  </ion-item>
  <ion-item>
    <ion-label>Neueste zuerst</ion-label>
    <ion-radio (click)="sortchange()"value="9"></ion-radio>
  </ion-item>
  <ion-item>
    <ion-label>Preis aufsteigend</ion-label>
    <ion-radio (click)="sortchange()"value="1"></ion-radio>
  </ion-item>
</ion-list>
`
})
class PopoverPage {

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

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

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

A:

Hey thanks everybody for your answer.
Put I used some ionic specific API to solve it.
I was creating the Child Popover via
presentPopover(ev) {

let popover = this.popoverCtrl.create(PopoverPage, {});

popover.present({
  ev: ev
});

Then there is some listener from Ionic which solves my Problem.
popover.onDidDismiss(data => {
//Can Use Data which is passed by Popover
});
