Problem with save()

Ok, after a while i successfull built something that seems to work:

function onInit(){
  
  var wifi = require("Wifi");
  wifi.connect("ssid", {password: "password"},
   function(err){if(err)console.log(err);
                 else {
                   console.log("connesso!");
                   var http = require("http");
                   http.createServer(function (req, res) {
                   res.writeHead(200);
                   res.end("Hello World"); 

                   }).listen(8080);}});
  wifi.save();

  }
save();

Since @tve pointed me to the good explanation of @allObjects things are slightly more clear.
Thanks everyone!
