Backbone Collections Custom Events with jQuery

Can Collection instance be binded to a custom event? I tried it with jQuery: $(collectionInstance).on(eventsmap).

When I then try to check registered events:

console.log($.data(collectionInstance, 'events'));

I get all custom events I bound to an instance.

But $(collection).trigger('customevent'); doesn't fire this customevent and event handler is not called.

When I try the same with Backbone.View I can trigger custom events whithout any problems. Why is like that? Am I missing something?

Backbone collections have Backbone.Events mixed in so collections have on, off, and trigger methods. You want to use those methods rather than trying to wrap the collection in jQuery:

collectionInstance.on('event', callback, context);
// One by one until you're done

and then elsewhere:

collection.trigger('customevent');
