> DatePicker fails to notify component update when OnChangeAjaxBehavior is used on the target input.
> It works well with AjaxFormComponentUpdatingBehavior.
> The root cause seems to be in the Wicket.ChangeHandler added by the OnChangeAjaxBehavior, which hides user handler while the DatePicker calls onchange handler directly (wicket-date.js:186):
> if (field.onchange != null && typeof(field.onchange) != 'undefined') field.onchange(); 
> Possible fix could be dispatching onchange Event instead of direct handler invocation. 
> Yet I don't know what is purpose of Wicket.ChangeHandler here...
