DatePicker Observable that fires when calendar beginDate is selected?

[Defmetalhead]

I have a calendar with a "clear" button in the header. I need a listener on the calendar that fires anytime a date is active(or when beginDate has been selected). I tried "dateChange", but it only fires when both dates have been submitted. Any thoughts on how I would listen for "beginDate" selection before "endDate" is selected?

Essentially I need an event to activate the header clear button as soon as the first date is selected that will allow the user to clear selected dates even though end date was not selected.

It's a new feature. You can implement it
