title: Show info window on map loaded with ngmap
body: <p>I'm using ng-map and typescript.
  This is my template :</p>
  
  <pre><code>&lt;map on-tilesloaded="showInfoWindow('myInfoWindow')" center="{{model.adresseLatitude}}, {{model.adresseLongitude}}" zoom="15" style="height: 425px"&gt;
      &lt;marker id="gmapMarker" on-click="showInfoWindow('myInfoWindow')" position="{{model.adresseLatitude}}, {{model.adresseLongitude}}"&gt;
          &lt;info-window id="myInfoWindow"&gt;
              &lt;div ng-non-bindable=""&gt;
                  {{model.adresse}}
              &lt;/div&gt;
          &lt;/info-window&gt;
      &lt;/marker&gt;
  &lt;/map&gt;
  </code></pre>
  
  <p>When the map is loaded the infoWindow is shown on the top left of the map but it works fine when the marker is clicked.</p>
  
  <p>I would like that the infowindow open at the right place (on the marker) when the map is displayed.</p>
