How do i render a data on android from node.js/mongodb server

The post method works successfully, its just that i can't see the string that am sending from android to the server showing in the server

This is my code

protected String doInBackground(String... params) {
   postData(params[0]);
   return null;
   }

    @Override
    protected void onPostExecute(String s) {
        pb.setVisibility(View.GONE);
        Toast.makeText(getApplicationContext(), "Your Post has been successfully posted",
                Toast.LENGTH_SHORT).show();
    }

    public void postData(String titleToSend){
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost("http://ift.tt/1HloeL3");

    try{
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("title", titleToSend));
        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = client.execute(post);
    }catch (ClientProtocolException e){
        e.printStackTrace();
    }catch (IOException e){
        e.printStackTrace();
    }
}

The onClick listener code

public void onClick(View v) {
            String tit = null;

            if(title.getText().toString().length()<1){
                Toast.makeText(getApplicationContext(), "Please Fill in all fields", Toast.LENGTH_SHORT).show();
            }else{
                pb.setVisibility(View.VISIBLE);
                myTask task = new myTask();
                task.execute(title.getText().toString());
            }
}

The data-type name in the server is title, so what the user input in the EditText should go to the title field.

The backend api.js

api.route('/')
        // GET method to get list of ads
        .get(function(req, res) {
            Ad.find({}, function(err, ads) {
                if(err) {
                    res.send(err);
                    return;
                }
                res.json(ads);
            });
        }) 

        // POST method to post an ad to the database
        .post(function(req, res) {
            var ad = new Ad({
                title: req.body.title,
                photos: req.body.photos,
            });
