Select Record in Datagrid and Zoom to Point

I modified one of the samples which uses the FindTask and displays the results in a Datagrid. When the Datagrid is click the map zooms to the extent of the selected feature.
I changed the map service from a Tax Parcel (polygon) service to the Cities (point) service.
Everything works except for the zoom to on selecting a record in the Datagrid. I assume the issue has to do with the geometry type.
