MarkerclusterでGoogleマップのマーカーをクリックしたときのデータを表示

Question

Googleマップのmarkerclustererマーカーがクリックされたときにカスタムデータを表示する方法を工夫しようとしていますが、

マイmarkerclustererコードは次のようになりますが、マーカーをクリックしてイベントをキャプチャでの私の試みが機能していません。

var markerClusterer = null; 
var map = null; 
var imageUrl = 'http://chart.apis.google.com/chart?cht=mm&chs=24x32&' + 
    'chco=FFFFFF,008CFF,000000&ext=.png'; 
google.maps.event.addDomListener(window, 'load', initialize); 

function refreshMap() { 
    if (markerClusterer) { 
     markerClusterer.clearMarkers(); 
    } 
    var markers = []; 
    var markerImage = new google.maps.MarkerImage(imageUrl, 
     new google.maps.Size(24, 32)); 
     /* 
    for (var i = 0; i < 1000; ++i) { 
     var latLng = new google.maps.LatLng(data.photos[i].latitude, 
      data.photos[i].longitude) 
     var marker = new google.maps.Marker({ 
     position: latLng, 
     icon: markerImage 
     }); 
     markers.push(marker); 
    } 
    */ 
    for (var i = 0; i < numItemsToShow; ++i) { 
     var latLng = new google.maps.LatLng(itemsToShow[i].lat, itemsToShow[i].long); 
     var marker = new google.maps.Marker({ 
     position: latLng, 
     icon: markerImage 
     }); 
     markers.push(marker); 
    } 
    var zoom = parseInt(document.getElementById('zoom').value, 10); 
    var size = parseInt(document.getElementById('size').value, 10); 
    var style = parseInt(document.getElementById('style').value, 10); 
    zoom = zoom == -1 ? null : zoom; 
    size = size == -1 ? null : size; 
    style = style == -1 ? null: style; 


    markerClusterer = new MarkerClusterer(map, markers, { 
     maxZoom: zoom, 
     gridSize: size, 
     styles: styles[style] 
    }); 
} 

function initialize() { 
    map = new google.maps.Map(document.getElementById('map'), { 
     zoom: 2, 
     center: new google.maps.LatLng(39.91, 116.38), 
     mapTypeId: google.maps.MapTypeId.ROADMAP,

      {"featureType":"road","stylers":[{"lightness":20}]}] 
    }); 
    var refresh = document.getElementById('refresh'); 
    google.maps.event.addDomListener(refresh, 'click', refreshMap); 
    var clear = document.getElementById('clear'); 
    google.maps.event.addDomListener(clear, 'click', clearClusters); 

    google.maps.event.addListener(markerClusterer, 'click', function() { 
     // do something with this marker ... 
     this.setTitle('I am clicked'); 
    }); 

    refreshMap(); 
} 

function clearClusters(e) { 
    e.preventDefault(); 
    e.stopPropagation(); 
    markerClusterer.clearMarkers(); 
}

これは、私の作品は、クラスタのアイコンをマウスオーバーしたときならば（それは、情報ウィンドウを開きますクラスタアイコンをクリックすると、クラスタ境界にズームするのがデフォルトの動作となります。クラスタアイコンのツールチップ/タイトルの変更が見えにくくなります）：

var infoWindow = new google.maps.InfoWindow(); 
google.maps.event.addListener(markerClusterer, 'mouseover', function (cluster) { 
    // do something with this cluster ... 
    infoWindow.setContent("Mouseover<br>"+cluster.getCenter().toUrlValue()); 
    infoWindow.setPosition(cluster.getCenter()); 
    infoWindow.open(map); 
});
