mongodb json into json

Im trying to get a json obj into a json table (via node js)

in the end it should look like (2 layered object)

{
  "Name": "bla",
  "List": "bla",
  "info": {
      "info1": "bla",
      "info2": "bla"
   }
  "Adress": "bla"
 }

i'll get the info just via

info = get.body;

i'm adding it via

db.collection('profiles', function(err, collection) {
    collection.update({"email": email},{$set: item}, function(err, result)

it results in an one layered json object

Question Closed

solution:

var info = req.body;
var insert = { "contact_info": info };
