your code should look something like this:
google.visualization.events.addListener(geochart, 'regionClick',
function(eventData)
{
alert('You clicked on a region named: ' + eventData.region);
});
the eventData (as you called it) returns an object named region that hold
an ISO-3166 name of the region clicked.
if you want the exact position of the mouse where you clicked you'll need
to use the window event.
