Scheduler timeline view is not able to set a link anymore

We used to work with timelineview 3.7
Now (4.3), the event_bar_text is not working anymore.
The text is displayed, but when clicking on the link, an update event is fired.

            var book_link = "<a href=\"admin.php?mod=dashboard&context=booking&id="+event.res_id+"\">"+event.res_id+"</a>";
			return book_link;

How can we make this link clickable again?
We tried to disable the save (unwanted) but even then the action (link) is not executed.

we’ll check the issue, i’ll give you an update later today
