attachEvent in jetview init() not working

I have multiple jet views, one view is a composite of three drop down / combo / suggest.

Each successor combo is depedenct on the previous. They’re linked combobox’s which when the parent changes (onChange) the child listens and updates it s contents aqccordingly.

Now I also have a TicketView which is rendered a bit later in the widget-flow.

It too has attachEvent(’‘onChange’) in it’s init() but it’s not working?!?!

When I console.log() the comboID it’s undefined.

Arewidgets only allowed a single event listener? It makes no sense the combo’s can somehow attachEvent() with their siblings, and an view further down the DOM can’t? What am I missing?
