I've got a Leaflet map that I am creating polygons, and I am trying to enable click events for them.

On the properties tab of the Leaflet element, in the Events section, I have identified a handler for the OnClick event, LeafletOnClick.  

I have specified MouseEvent (type is the Leaflet MouseEvent structure), as the handler for that event, (the input parameter of my LeafletOnClick action).  (My LeafletOnClick event for now is just coded to display a message that I have clicked the polygon).

The polygons are all created correctly, they all appear in their correct colors, positions, etc., and when I hover over one, the 'hand' icon changes to the 'pointing finger' icon, indicating it is recognizing the polygon element.

But when I click on it, it does not appear to fire the LeafletOnClick action.  I've even set a breakpoint inside the action, and it never hits it in debug mode, so it appears to not even register the click.

I've installed the Leaflet Demo, and it appears I'm doing everything that the marker click does in that demo (the demo does not have a polygon click).  Is there something I'm missing to get the LeafletOnClick to register when clicking one of the polygons?
