Subject: [PATCH] Extend checkAndSetDefaultValue for passing the called event

Extend checkAndSetDefaultValue for passing the called event. Custom getValue function get a parameter with the event caller.
evt.target will hold the <input> witch call the event. So you can check wich input field has fired the event and initilize the datepicker.
