Mongoose update query not working with node.js

Question

First I am making entries in mongodb by:

var device = new Device(inputDetailsJson); //device model instance

device.save(function(err) { 
                            if (err) {
                                res.send(err);
                            } else {
                                res.write('Successful');
                                res.end();
                            }

                        });

This is the device model:

// Dependencies
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

// Schema Definition
var deviceSchema=new Schema ({
    "deviceId":{ type : String , unique: true},
    "version":{ type : String },
    "manufacturer":{ type : String },
    "modelname":{ type : String },


});

// Model
module.exports = mongoose.model('de', deviceSchema);

This is the inputDetailsJson:

{   
            "deviceId":"3236172417",
            "version":"5.2.3",
            "manufacturer":"abc",
            "modelname":"example"
}

These details are getting entered correctly, but when I try to update something, it reflects no changes.

var device=new Device();
device.update({deviceId:"3236172417"},{modelname:"test"}
,function(err) {
if (err) {
            return console.error(err);
        }
else{
res.write('successful');
res.end();

It displays 'successful' even though no changes are made in the mongodb database.

var Device = require('your device model file');
Device.model.findOneAndUpdate({
       deviceId:"3236172417",
},{$set:{modelname:"test}},function(err, user) {

});

TypeError: Device.findOneAndUpdate is not a function

For updating the device you don't need to create a new device, using var device=new Device();

you should simply update, same as you try to find a document.

Device.update({deviceId:"3236172417"},{modelname:"test"}
,function(err) {
if (err) {
            return console.error(err);
        }
else{
res.write('successful');
res.end();
