Addition of named array breaks Kendo dataSource bind to JSON

Question

I'm binding a JS KendoUI dropdownlist to JSON (not using a model) which recently has been changed by adding a named array to the object (in efforts to format the JSON for a Kendo TreeView control). This broke a few things of course. The original JSON format looked like this (an array of objects):

[
 {
   "COLUMN_NAME": "OBJECTID",       
   "DATA_TYPE": "esriFieldTypeOID",              
   "CATEGORY": "Feature Data"
  },
  {
   "COLUMN_NAME": "Brand",       
   "DATA_TYPE": "esriFieldTypeString",              
   "CATEGORY": "Feature Data"
  },...    
]

now it looks like this (an object with a named array, with objects):

{
 "Hydrant": [
  {
   "COLUMN_NAME": "OBJECTID",       
   "DATA_TYPE": "esriFieldTypeOID",              
   "CATEGORY": "Feature Data"
  },
  {
   "COLUMN_NAME": "Brand",       
   "DATA_TYPE": "esriFieldTypeString",              
   "CATEGORY": "Feature Data"
  },...
],
"DisplayField": "Description",
"DefaultField" : "HydrantID"    
}

I assumed I could simply define the schema to "Hydrant" or set the dataText/ValueFields to "Hydrant.COLUMN_NAME" but no luck. What am I overlooking? I am binding this JSON format response to a dropdownlist using the "COLUMN_NAME" to populate it.

bonus: how could I use the "DefaultField" to set the default selection in the dropdownlist?

Thanks in advance!

You can use the schema.data field of the DataSource configuration to identify the field from the response to use for its data:

schema: { data: 'Hydrant' }
