Bind columns to child properties

[Robert]

I have a grid which I need to bind some columns to JSON child properties

$("#grid").kendoGrid({
  dataSource: {
   data: [
     { time: "1:00", city: "Chicago", temperature: { value: 89, displayString: "89 F" } }
   ]
  },
  columns: [
   { field: "time", title: "Time" },
   { field: "city", title: "City" },
      { field: "temperature.displayString", title: "Temperature" }  ]
});

The syntax is valid - I just need to watch for typing errors. 

Thanks!
