title: How to call parent method from Modal
body: <p>Is it possible somehow to call method of controller that called modal?</p>
  
  <p>Basically I have HomePage in which I called UserInfoModal. Can I somehow call HomePage.changeStatus from UserInfoModal?</p>
  
  <p>Parent:</p>
  
  <pre><code>@Component({
     selector: 'page-home',
     templateUrl: 'HomePage .html',
  })
  
  export class HomePage {
     ...
     createModal() {
        let myModal = this.modalCtrl.create(UserInfoModal, item, 
                                           this.supervisor);
        myModal.present();
     }
  
     changeStatus(item) {
        ...
     }
  }
  </code></pre>
  
  <p>Modal:</p>
  
  <pre><code>@Component({
     templateUrl: 'UserInfoModal.html',
     selector: 'userinfo-modal'
  })
  
  export class UserInfoModal{
     ...
     changeParentStatus() {
        // call 'changeStatus()' from parent
     }
  }
  </code></pre>
