Nodejs XMPP Component Usage

I'm trying to create a nodejs component using node-xmpp-component. But I keep getting error code 400, type modify, bad request, but I don't see anything wrong with my iq message.

My ejabberd configuration:

{5282, ejabberd_service, [ 
    { hosts, ["nodejs.myejabberddomain"], [{password, "admin"}] } 
 ]}

My nodejs Component code:

var Component = require('node-xmpp-component')
  , ltx = require('node-xmpp-core').ltx;


var component = new Component({
  jid       : "nodejs.myejabberddomain",
  password  : "admin",
  host      : "localhost",
  port      : "5282"
})

component.on('online', function() {
    console.log('Component is online')

    var iq = new ltx.Element('iq',{type:'set',id:'reg2', to: 'myejabberddomain'})
                .c('query',{xmlns:'jabber:iq:register'});

    component.send(iq);

})

component.on('error', function(e) {
    console.error(e)
    process.exit(1)
})

I'm not sure if I have any ejabberd configuration missing, or if I have any problem with my nodejs component connection or if this nodejs-xmpp-component is "broken"!

Anyone knows what I'm doing wrong? Any tips?

I've changed from ejabberd to prosody, but at first the registration was returning "service-unavailable".

So I had to go on prosody chat, and user called Zash helped me creating a module named mod_register_from_component.

In the lines 182 to 185 I changed the original mod_register to:

module:hook("iq/host/jabber:iq:register:query", function(event)
   local session, stanza = event.origin, event.stanza;

   if session.type ~= "component" then

Then in the prosody.cfg.lua in the modules_enabled I added my new module (and commented the original one)
