I want to append 4 icons each event on the calendar. Each icon should calls different function on click event. To be honest, I am not too good in CSS. I have tried the below
I think you need to use the .on() function to register an event handler to your icons.
.on()

The click events get triggered and are handled appropriately with the .on() handler. Let me know if this helps!
