How can I get a field when I use JSON api whith more than one field?

Hi,

I am trying to get some json data using JSON API.

I configure in a variable obs_list to get 2 fields:
$.objetos[].id_objeto*
$.objetos[].nome*

But I cannot use these 2 fields in panel title or query.

I can only access the first field, using obs_list.

How can I get diferents fields variable in panel name and in query ?

Please share sample json data
