Retreiving custom properties for datasource field

[jwbst21]

I have been searching for an answer in the reference documentation and in the forums with no luck.

I need to create custom properties/attributes for fields defined in my data source config (.ds.xml). Example:

<field name="id" customProperty="somevalue">

How do I access that custom value in the client (JS)? I don't see it in the actual field definition, and don't see a method that would allow me to retrieve it.

isc.DS.get(dsId).getField(fieldName).customProperty

This is not working. When looking at the response from the data source loader, the custom properties are not in the field definitions. Is there a property on the data source configuration that I need to set to send these properties back in the response with each field?

No, it's automatic.
