Possibility to hide picker from overlayComponent

[horprogs]

I use custom overlayComponent and it would be cool to make it possible to have a callback inside overlayComponent function to hide day picker. For example: I have a custom button "Clear date" and I want to reset date and close picker. Now I don't see any way to hide picker manually.

Solution
Add hidePicker function argument to overlayComponent

Or maybe does another way exist to do it?
Thank you
