Custom Field Data not showing up with API call.

Custom Field Data not showing up with API call.

I am working on an application that can create new tickets and read ticket details of current ones. When I submit a ticket with custom field data it creates correctly and I can view the newly created ticket. But the custom field data shows up as a empty field.

This is how it is formatted when I submit the ticket. 
      cf : {
        cf_store : data.store
      }

This is what I see when I try to view the ticket. 
cf: Object { }


Do I need to format my GET request a special way to view Custom Field Data?

Thank you.
