Question

When entering a date manually, i.e. without using the day picker, no event is triggered. It should be possible to enter dates manually without using the picker.

but you have to check if date is valid, if is not in onDayChange callback is passed undefined as value, if you manually set 2018-09-01 it works as expected.
