Nested webix components with backbone

Webix JS
1

Hi,

I have created a nested component dynamically and tried to attach an event to it, once its rendered. I failed to find the element in this.getChild(…) , but was able to find using $$(…).

Can anybody help me understand what exactly is happening?
Why is this.getChild() not returning the element?

And how can I get the model cid in callback??
