Google Map InfoWindow Content Binding

I'm new with Google map. I'm having problem in rebinding the data in my infowindow.

When I close the window using the "x" button in the upper right of the infowindow,
then open it again, all of the updated contents of the infowindow will load again to its initial state instead of the latest update? What I want is that when I close the
infowindow, the infowindow must have the latest data.

Update your function to be:

function bindInfoWindow(marker, map, infoWindow, html) {
    google.maps.event.addListener(marker, 'click', function() {
         infoWindow.setContent(html);
         infoWindow.open(map, marker);
    });
}
