webix combo

Hi webix team,

I am trying to bind data to combo on item click. But when I bind options on item click event. I have to click twice. In order to see the option list.

I can bind data onAfterRender event for performance(in case of large data).

And in above scenario I have ajax call in order to fetch the data
