Datatable autoConfig issue

Hi Webix team,

https://snippet.webix.com/g5jjnzc3

In this snippet I am using autoConfig true to datatable, but I am not hetting onAfterRender function.
I don’t want to use columns and also I want to attach data onAfterRender using webix.ajax function.
How to do this?

Thanks,
Mira
