On enter datePicker widget not working

Hi,

I have a standard Mendix datePicker with an On Enter event on it.

When I click the date field to type the date the On Enter microflow is called. However, when I click the calendar icon to pick a date the On Enter microflow is not called.

Anyone any idea what this could be? Is it a bug in the widget? Is there a way I can make it work?

Thanks for your answers!
