Express Busboy on File Event not firing - node.js

Question

I am trying to make busboy work with my express code, but none of its events are firing,
there are no silly mistakes like non-matching input field names etc.
Here is
app.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var index = require('./index');
var liveupload = require('./liveupload');
var app = express();
// view engine setup
app.set('view engine', 'pug');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(express.static(__dirname + '/bower_components/dropzone/dist'));
app.use('/', index);
app.use('/liveupload', liveupload);
app.listen(3000, function () {
console.log('Example app listening on port 3000!')
})
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found SIR');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
This is desired action : liveupload
var express = require('express');
var router = express.Router();
var Busboy = require('busboy');
router.post('/', process_upload);
function process_upload(req, res, next){
var busboy = new Busboy({ headers: req.headers });
// Listen for event when Busboy finds a file to stream.
busboy.on('file', function (fieldname, file, filename, encoding, mimetype) {
console.log("In bus boy");
// We are streaming! Handle chunks
file.on('data', function (data) {
// Here we can act on the data chunks streamed.
console.log("Chunk mila");
});
// Completed streaming the file.
file.on('end', function () {
console.log('Finished with ' + fieldname);
});
});
busboy.on('field', function(fieldname, val, fieldnameTruncated, valTruncated, encoding, mimetype) {
console.log('Field [' + fieldname + ']: value: ' + inspect(val));
});
console.log("out of busboy");
res.sendStatus(200);
}
module.exports = router;
And here is the UI which uploads the file.
<script language="JavaScript" type="text/javascript" src="javascripts/jquery.min.js"></script>
<script>
$(function(){
Dropzone.options.himanshu = {
paramName: "file",
maxFilesize: 5,
addRemoveLinks: true,
dictResponseError: 'Server not Configured',
acceptedFiles: "*.*",
init:function(){
var self = this;
// config
self.options.addRemoveLinks = true;
self.options.dictRemoveFile = "Delete";
//New file added
self.on("addedfile", function (file) {
console.log('new file added ', file);
});
// Send file starts
self.on("sending", function (file) {
console.log('upload started', file);
$('.meter').show();
});
// File upload Progress
self.on("totaluploadprogress", function (progress) {
console.log("progress ", progress);
$('.roller').width(progress + '%');
});
self.on("queuecomplete", function (progress) {
$('.meter').delay(999).slideUp(999);
});
// On removing file
self.on("removedfile", function (file) {
console.log(file);
});
}
};
})
</script>
<link href="stylesheets/dropzone.css" rel="stylesheet"/>
<form action="/liveupload" method="post" class="dropzone" id="himanshu" enctype="multipart/form-data" >
<div class="fallback">
<input name="file" type="file" multiple />
</div>
</form>
I have tried numerous ways, but still cant figure out why busboy is not working.
any help will be greatly appreciated

Problem was with liveupload.js
here is corrected code -
var busboy = new Busboy({ headers: req.headers });
// Listen for event when Busboy finds a file to stream.
busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
console.log("In bus boy");
// We are streaming! Handle chunks
file.on('data', function(data) {
// Here we can act on the data chunks streamed.
console.log("Chunk mila");
});
// Completed streaming the file.
file.on('end', function() {
console.log('Finished with ' + fieldname);
});
});
busboy.on('field', function(fieldname, val, fieldnameTruncated, valTruncated, encoding, mimetype) {
console.log('Field [' + fieldname + ']: value: ' + inspect(val));
});
busboy.on('finish', function() {
console.log("out of busboy");
res.sendStatus(200);
});
req.pipe(busboy);
}
