title: NativeScript ListView won't display my data
body: <p>I'm really new to NativeScript, decided to do a basic app with it... So I create a service using HttpClient... Anyway, when i do console.dir(events) the data displays in the console, when i use a label, it displays too but it just wont show in my ListView 
   Here is my template:</p>
  
  <pre><code>    &lt;StackLayout class="page"&gt;
      &lt;ListView [items]="events" class="list-group"&gt;
          &lt;ng-template let-item="item"&gt;
              &lt;Label [text]="item.theme"
                     class="list-group-item"&gt;&lt;/Label&gt;
          &lt;/ng-template&gt;
      &lt;/ListView&gt;
  &lt;/StackLayout&gt;
  </code></pre>
  
  <p>My conponent has this:</p>
  
  <pre><code>    constructor(private eventService: EventService) { }
  
        ngOnInit() {
          this.getEvents();
        }
  
  
          getEvents(){
              this.eventService.loadEvents().subscribe(
                  data =&gt; {
                      this.events = {...data};
                      console.dir(this.events)
                  },
                  error =&gt; this.error = error
              );
          }
  </code></pre>
  
  <p>and my service is this:</p>
  
  <pre><code>constructor( private http: HttpClient ) {}
  
      loadEvents(){
          return this.http.get&lt;Event&gt;(this.baseUrl)
              .pipe(
                  retry(3),
                  catchError(this.handleError)
              );
  
      }
  
      private handleError(error: HttpErrorResponse) {
          if (error.error instanceof ErrorEvent) {
              // A client-side or network error occurred. Handle it accordingly.
              console.error('An error occurred:', error.error.message);
          } else {
              // The backend returned an unsuccessful response code.
              // The response body may contain clues as to what went wrong,
              console.error(
                  `Backend returned code ${error.status}, ` +
                  `body was: ${error.error}`);
          }
          // return an ErrorObservable with a user-facing error message
          return new ErrorObservable(
              'Something bad happened; please try again later.');
      };
  </code></pre>
