Grid property "items" databinding issues

Hi, I would like to advice that Grid components doesn’t do correctly databinding on property “items” using TemplateModel.

I’m using Vaadin 13 and when I try to insert a grid vaadin component inside html template it doesn’t populate with data collection inside model defined using property “items”.
I’ve tried both single way and two way data binding with failure results and I’ve been forced to make Grid directly using Java Flow API.

Could you solve this issue with Grid (non pro) component?
