Background Images in webix Jet

Hi, i have this code: https://snippet.webix.com/1fqkw6j1
What I need is to put 4 images in every template I create, I tried with template in the line 52 but it’s not working. Please help!

the best way is to use function template

in case of simple data you can use string template too
template: "#title#<img src='#src#' />"

Thanks @intregal it was very helpful
