uploading file to ftp server in node.js

I am trying to upload a file on ftp server using node.js as below-

I am using library- https://github.com/sergi/jsftp

var fs = require('fs');
var Ftp = new JSFtp({
    host: "ftp.some.net",
    port: 21, // defaults to 21
    user: "username", // defaults to "anonymous"
    pass: "pass",
    debugMode: true // defaults to "@anonymous"
});

Uploading file-

exports.UploadToFtP = function (req, res) {
     Ftp.put('public/Test.html', '/Test/index.html', function (err) {
            if (!err)
                res.send(200);
            else
                res.send(err);
        });
};

I tried uploading file with this method above and it responds me back with 200 OK . But I get no file on server. Is this has to do something with connection time out of server ? Why this is not writing file on server?
