I have try to create a test project for use Open Layers 3 with the new ionic 2 but it isn't work

This is my layout:

<ion-navbar *navbar>
  <button menuToggle>
    <ion-icon name="menu"></ion-icon>
  </button>
  <ion-title>Mappa</ion-title>
</ion-navbar>


<ion-content padding class="map-page">

    <div id="map" class="map"></div>

</ion-content>

And this is my controller:

import {Page} from 'ionic-angular';


@Page({
  templateUrl: 'build/pages/map/map-page.html'
})
export class MapPage {


    constructor(){

        this.test = ["uno", "due", "tre"];



        // var layer = ga.layer.create('ch.swisstopo.pixelkarte-farbe');

     //    var map = new ga.Map({
        //     target: 'map',
        //     layers: [layer],
        //     view: new ol.View({
        //       resolution: 500,
        //       center: [670000, 160000]
        //     })
        //   });

     //    this.map = map;


     console.log(this.map);

      var projection = ol.proj.get('EPSG:3857');

      var map = new ol.Map({
            target: this.map,
            layers: [
              new ol.layer.Tile({
                source: new ol.source.OSM()
              })
            ],
            view: new ol.View({
              center: ol.proj.transform([8.92471, 46.07257], 'EPSG:4326', 'EPSG:3857'),
              zoom: 14
            })
          });

    }

}

I have also imported this library on my application:

  <link md-href="build/css/app.md.css" rel="stylesheet">
  <link wp-href="build/css/app.wp.css" rel="stylesheet">  
</head>
<body>

  <ion-app></ion-app>

  <script src="cordova.js"></script>
  <script src="build/js/app.bundle.js"></script>


</body>
</html>

In a old project with ionic 1 this code is working. Any suggestion?

THX.

Hi simple solution just use settimeout !

setTimeout(() => {

            var map = new ol.Map({
                layers: [
                    new ol.layer.Tile({
                        source: new ol.source.OSM()
                    })
                ],
                target: 'openlayers',
                controls: ol.control.defaults({
                    attributionOptions: ({
                        collapsible: false
                    })
                }),
                view: new ol.View({
                    center: [0, 0],
                    zoom: 2
                })
            });

        }, 500);
