Markerclusterer and infowindow v3 is not working properly - google-maps

Question

I have used the sample code from google for markerclusterer. I added a code to display the coordinate of the marker in an infowindow for the markerclusterer v3 but the problem is it only loads the last marker latlang into the window: Can anyone help to resolve this issue.
function initialize() {
var center = new google.maps.LatLng(37.4419, -122.1419);
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 3,
center: center,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
var markers = [];
for (var i = 0; i < 100; i++) {
var dataPhoto = data.photos[i];
var latLng = new google.maps.LatLng(dataPhoto.latitude,
dataPhoto.longitude);
var info = dataPhoto.photo_id;
var marker = new google.maps.Marker({
position: latLng
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setPosition(latLng);
infowindow.setContent(latLng.toString());
infowindow.open(map,marker);
});
markers.push(marker);
}
var markerCluster = new MarkerClusterer(map, markers);
}
google.maps.event.addDomListener(window, 'load', initialize);
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50)
});
</script>`

Answer 1

Here I found the answer using the hint #geocodezip provided. The event addListener should be changed as follows:
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(marker.position.toString());
infowindow.open(map, marker);
}
})(marker, i));
