vaadin-grid button columns

Hello …
I have tried to build a small web application with vaadin-grid and Polymer today.
Now I need to add a column with buttons (paper-button or vaadin-button if exists) inside my grid.
This is my Code so far:

I used iron-ajax like in the tutorial video to load my items and bind it to my grid .
So what would be the recommended way to add a column which holds a button for each row ?

Hi,

Tomi answered a similar question just recently, with examples for both vaadin-grid 1.x and 2.0-pre versions:

You should be able to follow the examples there and replace the checkboxes with buttons instead.
