Yeah, I didn't noticed that, but you are right. However, after today update to 3.1.1 (or you did something) now, IT'S WORKING!!!!!!
Thanks a lot.
P.S. As Abierto/Cerrado is within your function, how to set color switch for that (green/red)? I guess that I can add the class to - return "Cerrado"; (something like --> return "Cerrado".addClass("bg-danger");), and (bg-success) for Abierto, but I'm not sure how to do it.
