For once again I found the answer to my own question! Maybe you guys hire me to populate the form with self-made questions and answers! :D

It is invalidateCache():

public void reloadCalendarData() { // on current view
	invalidateCache();	
		fetchData(getFetchCriteria(), new DSCallback() {
			@Override
			public void execute(DSResponse response, Object rawData, DSRequest request) {
				setData(response.getData());	
			}
		});
	}

Thanks a lot
