Greetings,
I am a student who uses Moodle and I've encountered a bug in the app that happens in New event screen. When I touch the Date bar, nothing happens, but when I touch a some random point on the screen, the Date window flashes for a second.

Steps to reproduce:
1) Open Moodle appp
2) Go to Calendar
3) Touch the "plus" button
4) Touch Date bar
5) Nothing happens
6) Touch a random point on the screen
7) Date window flashes for a second

What I've expected:
Touching the Date bar opens up Date window, so I can be able to enter the date and time.

What actually happens:
What I've described.
