Open lightbox in month view

I’ve a problem with custom lightbox in month view.
In all other views works fine (week, day, unit), but in month view the lightbox doesn’t show.

scheduler.showLightbox = function(id) { openModalCustom(id); };

How can I do?


Please show your code or provide with a demo so we could reproduce the issue and understand what’s happening.
By default showLightbox event works properly in all views.
