I have different restaurant makers on maps.  
When I click one marker, it is supposed to show restaurant name and  
address after fetching from server at run time.

Currently I am doing this…  
restaurant#{restaurant.id}marker.openInfoWindowHtml("#{restaurant.name}");

It is a problem when there are so many restaurants in map.

How can I fetch at runtime?

Thanks.
