How to save the data in the database using mongoose/mongodb?

my code consists of server.js file to create a node+ express server api. the server.js file consists of models that I have created and the routes with GET, POST methods.

server.js

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
var morgan = require('morgan');
var mongoose = require('mongoose');
var cors = require('cors');

mongoose.connect('mongodb://localhost/contactlist');

app.use(morgan('dev'));
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({type:'application/vnd.api+json'}));
app.use(methodOverride());
app.use(cors());

app.use(function(req,res,next){

    res.header("Access-Control-Allow-Origin","*");
    res.header("Access-Control-Allow-Methods", "DELETE,PUT");
    res.header("Access-Control-Allow-Headers", "Origin,X-Requested-With, Content-Type, Accept");
    next();
});

var Contact = mongoose.model('Contact',{
    name:String,
    email:String,
    number:Number,
    address:String
});

//Routers
//get
app.get('/contacts',function(req,res){
    console.log('inside get router fetching the contacts');

    Contact.find(function(err, contacts){
        if(err)
        res.send(err);
        res.json(contacts);
    });

});

//post---->get

app.post('/contacts',function(req,res){
    console.log('creating the contacts');

    Contact.create({
        name:req.body.name,
        email:req.body.email,
        number:req.body.number,
        address:req.body.address,
        done: false
    },function(err,contact){
        if(err)
        res.send(err);

        Contact.find(function(err,contact){
            if(err)
            res.send(err);
            res.json(contact);
        });
    });
});

app.listen(8080);
console.log('App listening on port 8080');

Then I have created my service class where I fetch my data from server. I don't have any problem in this.It is working absolutely fine.

Then comes my 2 pages where in the first page I create a contact list and in the second page I get that list from the server/db.

Please help me out that why am I not able to get the data from the db and post the correct data. The data that is posted in the db contains only Id and -v flag.
