public void onCallbackCompleted(String data) {
        Gson gson = new Gson();
        if(data != null) {
            HashMap<String, List<Brand>> output = gson.fromJson(
                    data,
                    new TypeToken<HashMap<String, List<Brand>>>() {
                    }.getType()
            );

            rawData = output.get("posts");
            simpleAdapter.clear();
            simpleAdapter.addAll(rawData.toArray());
            simpleAdapter.notifyDataSetChanged();
        }

    }
