Trigger when drop and drag Calendar

Hi all. How to update the calendar when drop and dragging it?

As you can see in the GIF below the Calendar will just go back to its original state when I press f5.

Which version are you using ?

erpnext 12.29.0
frappe 12.26.1

the issue is in erpnext/education/doctype/course_schedule/course_schedule_calendar.js

I tested it on erpnext 13.26.0 and it works fine :smiley:
