title: In angular-google-maps, how to show infoWindow via a mouseover event on marker?
body: <p>I am working on a project with angular-google-maps. 
  I wanted to add a mouseover event to markers, so I followed the tutorial in the angular-google-maps example folders.
  However, I can't get it work.
  Here is the Plunker link.

  <pre><code>        &lt;ui-gmap-windows show="show"&gt;
              &lt;div ng-non-bindable&gt;{{text}}&lt;/div&gt;
          &lt;/ui-gmap-windows&gt;
  </code></pre>
  
  <p>$scope.markersEvents = {
              mouseover: function (gMarker, eventName, model) {</p>
  
  <pre><code>                model.show = true;
  
                  $scope.$apply();
  
              }
  </code></pre>
  
  <p>};</p>
