wish of those help Your data property should be of array type so that you can add multiple objects with same object structure like:
code :
var obj = {
    "request_id": "8123",
    "lease_id": "",
    "renewable": false,
    "lease_duration": 4576,
    "data": [{
      "mynew": "123",
      "name": "sample"
    }, {
      "mynew": "xyz",
      "name": "newsample"
    }],
    "wrap_info": null,
    "warnings": null,
    "auth": null
};
var obj = {
  "request_id": "8123",
  "lease_id": "",
  "renewable": false,
  "lease_duration": 4576,
  "data": [{
    "mynew": "123",
    "name": "sample"
  }],
  "wrap_info": null,
  "warnings": null,
  "auth": null
};
var newData = {
  "mynew": "xyz",
  "name": "newsample"
};
obj.data.push(newData);
console.log(obj);

wish helps you You are using splice to properly remove an element from a javascript array:
code :
json.feeds.splice(0,1)
(function(){
    var json = {
        "feeds": [
            {"username":"abc","user":"abc","feed":{"description":"dss","id":660,"user_id":1}},
            {"username":"bcd","user":"bcd","feed":{"description":"dddd","id":659,"user_id":1}}
        ]
    };

    json.feeds.splice(0,1);
    console.log(json.feeds); // just to check that "feeds" contains only a single element
})();

Any of those help I am having problems trying to sort this on my own. , You can assign to an object property just like any other variable:
code :
j.my_item.total_price = "2222";
j['my_item']['total_price'] = "2222";
j.my_item['total_price'] = "2222";
j['my_item'].total_price = "2222";
