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:

<template is="dom-bind" id="app">
<iron-ajax auto
url="/api/grid/data"
handle-as="json"
method="POST"
last-response="{{gridItems}}"
debounce-duration="300"></iron-ajax>

<vaadin-grid id="grid" items="{{gridItems}}" selection-mode="multi">
<table>
<colgroup>
<col name="FNR" resizable/>
<col name="Planinhalt" resizable/>
<col name="Geschoss" resizable/>
<col name="Maßstab" resizable/>
<col name="Region" resizable/>
<col name="Gebiet" resizable/>
<col name="PLB" resizable/>
<col name="File"/>
</colgroup>
</table>
</vaadin-grid>
</template>

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: https://vaadin.com/forum/#!/thread/14377885/14382342

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