How to pass a "custom" array for iPhone in the remote push notification?

I saw that from 996 build the iPhone “custom” field bug is fixed, but it doesn’t work for me (I tried builds 1003 and 996) . This is my curl-code:

curl -X POST \  
 -H "X-Parse-Application-Id: XXXX" \  
 -H "X-Parse-REST-API-Key: XXXX" \  
 -H "Content-Type: application/json" \  
 -d '{ "channel": "news", "type": "ios", "data": {"custom" : {"type" : "11"} , "alert":"Hello World!"} }' \  
 https://api.parse.com/1/push  

On iphone in “onNotification” event I receive with this code:
custom:[]
In Parse support forum I received an answer that my curl-syntax is right.

So how can I pass the “custom” array to Corona application? Thanks [import]uid: 172733 topic_id: 35530 reply_id: 335530[/import]
