New Calender widget doesn't display new entry in calender widget

[Tamer Higazi]

Hi!
On my XIAOMI MI2 (ROM Version: MIUI JLB 7.0 Stable Build) I figured out that after creating a new appointment, it isn't being displayed in the calender widget.

Only if I restart the phone, it's being displayed in the widget on the screen.

please fix it.....
