Socket.get callback not triggered in socket.on function - node.js

Question

I've been stuck on this issue for a while the answer might be really basic but I fail to understand what the problem is. AFAIU It execute the function but doesnt trigger the callback and I dont know why.
My script aim to have both a tcp server to have a device (raspberry pi) that connect a tcp socket and a client to connect to a websocket on a sailsjs app.
I manage to have both this thing running on the following code, the problem is they only work separatly, simultanuously but separatly, when I try a get outside the socket everything works fine but when I do inside, the io.socket object is just piling up the get request in a requestQueue.
{ useCORSRouteToGetCookie: true,
url: 'http://localhost:1337',
multiplex: undefined,
transports: [ 'polling', 'websocket' ],
eventQueue: { 'sails:parseError': [ [Function] ] },

[ { method: 'get', headers: {}, data: {}, url: '/', cb: [Function] },
{ method: 'get', headers: {}, data: {}, url: '/', cb: [Function] } ] }
The code is the following :
//library to connect to sailsjs websockets
var socketIOClient = require('socket.io-client');
var sailsIOClient = require('sails.io.js');
//library to do the tcp server
var net = require('net');
// Instantiate the socket client (`io`)
// (for now, you must explicitly pass in the socket.io client when using this library from Node.js)
var io = sailsIOClient(socketIOClient);
// Set some options:
// (you have to specify the host and port of the Sails backend when using this library from Node.js)
io.sails.url = 'http://localhost:1337';
var server = net.createServer(function(tcpSocket) { //'connection' listener
//socket was sucessfully connected
console.log('client connected');
//notify on deconnection
tcpSocket.on('end', function() {
console.log('client disconnected');
});
// Handle incoming messages from clients.
tcpSocket.on('data', function (data) {
console.log(data.toString('utf8', 0, data.length));
//if data is PING respond PONG
if(data.toString('utf8', 0, 4)=='PING'){
console.log('I was pinged');
tcpSocket.write('PONG\r\n');
}
console.log(io.socket);//debugging purpose
//trigger a socket call on the sails app
io.socket.get('/', function (body, JWR) {
//display the result
console.log('Sails responded with: ', body);
console.log('with headers: ', JWR.headers);
console.log('and with status code: ', JWR.statusCode);
});
});
});
server.listen(8124, function() { //'listening' listener
console.log('server bound');
});

It looks like your socket isn't autoconnecting. Try connecting manually:
// Instantiate the socket client (`io`)
// (for now, you must explicitly pass in the socket.io client when using this library from Node.js)
var io = sailsIOClient(socketIOClient);
// Set some options:
// (you have to specify the host and port of the Sails backend when using this library from Node.js)
io.sails.url = 'http://localhost:1337';
var socket = io.sails.connect();
socket.on('connect', function() {
... connect TCP server and continue ...
});

I found a solution, I just got rid of sails.io.js and used plain socket.io it now works as intended feel free to explain though why it didnt in sails.io.js
//library to connect to sailsjs websockets
var socketIOClient = require('socket.io-client');
//var sailsIOClient = require('sails.io.js');
//library to do the tcp server
var net = require('net');
var socket=socketIOClient.connect('http://localhost:1337', {
'force new connection': true
});
var server = net.createServer(function(tcpSocket) { //'connection' listener
//socket was sucessfully connected
console.log('client connected');
//notify on deconnection
tcpSocket.on('end', function() {
console.log('client disconnected');
});
// Handle incoming messages from clients.
tcpSocket.on('data', function (data) {
console.log(data.toString('utf8', 0, data.length));
console.log(data.toString('utf8', 0, data.length));
//if data is PING respond PONG
if(data.toString('utf8', 0, 4)=='PING'){
console.log('I was pinged');
tcpSocket.write('PONG\r\n');
}
if(data.toString('utf8', 0, 4)=='test'){
socket.emit('test',{message : 'test'});
//io.socket.disconnect();
}
});
});
