title: Google maps api gm_bindings_ undefined
body: <p>I am making a list of the markers that I have under the map, and when a user clicks it should display that marker but it doesn't. I get a console error: Uncaught TypeError: Cannot read property 'gm_bindings_' of undefined </p>
  
  <p>Now I'm stuck and turning to you for help.</p>
  
  <p>Some code:</p>
  
  <pre><code>var infowindow = new google.maps.InfoWindow();
  map.addMarkers(allMarkers);
  jQuery(document).on('click','.address',function(){
          marker = allMarkers[this.id];
          infowindow.open(map, marker); //The error occurs on this line.
  });
  </code></pre>
