We have checked your query and response data was mapping in ListView properly . For your convenience, we have prepared a sample based on documentation and the same can be downloaded from below link,
Query 2: How do I parse out those extra properties from JSON object.
We have checked your requirement and if you want use data manager for rendering the ListView items, the returned data will be based on ListView field property values. So, we cannot return any additional property values.
