Found what I believe to be a mistake on the MSDN Windows 8 JavaScript ListView tutorial http://msdn.microsoft.com/en-us/library/windows/apps/br211837.aspx DataArray item property should be "description" instead of "text" so that the template correctly uses the description property of each object. Otherwise the template returns undefined.
