Event CHOP callback not cooking in perform mode

I’ve got an Event CHOP listening to a Midi In Map, the Event CHOP has a Callback DAT that changes works fine but when I’m in perform mode it looks like the Callback DAT python script is not executed.
Is there a way to force it to cook all the time?

The way to solve it was to add a Null CHOP with the Cook Type parameter set to Always after the Event CHOP
