Add button inside day cell and prevent dateClick when exists event

[tomimelo]

Im looking for a way to add a button inside future days cells, like a plus button to add new event. I tried with no success with dayCellContent and dayCellDidMount. I use the dateClick handler to add events to that specific day but I want a button to be more intuitive. I also want to prevent dateClick if its already an event on that day. Has anyone been able to do it or something similar?
