[visualization-api] geomap marker event not firing

[Theo Zizic]

 
Hello, I would like some help with the following. Everything works fine, 
data are obtained from a query, then a map is created but when I click on 
the markers nothing happens, (ie the link is not loaded)

Thanks for the Help 

PS I have already tried to execute the file from a server and not only 
locally but still the links do not fire.
