In the section Bind the Store data to Grid and Chart, before step 2 (auto columns), you need to select CarDataJson in the project inspector and set the 'model' attribute to carDataModel. Otherwise, trying to right-click 'grid' and use the 'Auto columns' option will generate the following error: Unable to read columns - the assigned store has no model or fields defined.
