I don’t like ('cause I don’t know) Javascript, that’s why I’m trying  
to figure out how to implement the whole GoogleMaps-part of my  
application using Ruby/Rails.

I’ve a problem registering events on markers:

[http://pastie.textmate.org/71697](http://pastie.textmate.org/71697)

The event-listener works for map-events if i use ‘@map’ instead of  
‘@my\_marker’ on line 15.

The big picture:  
I’d like to read latitude and longitude as soon as the user drags the  
marker to a location on the map.
