Can't call event in async mode

[ruiisidro]

I have this scenario:

1. I've created a collection to log some data.
   When a user posts to this collection I want to call a custom dpd-event where I will call an external service asynchronously. When the external call ends I want to finish up some details in the post data.

//this is the custom dpd-event
//file resources\cloudinarysrv\post.js
var cloudinary = require('cloudinary');

var done = ctx.done          // remember this to end the response (async)
ctx.done = function () { }      // dummy function for autoresponse (sync)

cloudinary.config({
  cloud_name: 'my_cloud_name',
  api_key: 'my_key',
  api_secret: 'my_secret'
});

cloudinary.v2.uploader.upload(ctx.body.ficheiro, function (error, result) {
  if (error) {
    cancel(error.message, 401);
  }
  else {
    console.log("resposta do  cloudinary");
    console.log(JSON.stringify(result));
    setResult(result);
  }
});

As to the collection:

//this is the collection
//resources\exchange\validate.js
var self = this;

if (self.logotipo) {
    dpd.cloudinarysrv.post({ ficheiro: self.logotipo }, function (result, error) {
        if (error) {
            self.logotipo = "upload error image default...";
            self.secureLogotipo = "upload error secured image default...";
        }
        else {
            console.log(JSON.stringify(result));
            console.log("já guardou na cloud e está de volta...");
//this should be get after the external call in dpd-event finishes but the call is not being done asynchronously
            self.logotipo = result.url;
            self.secureLogotipo = result.secure_url;
        }
    });
}
else {
    self.logotipo = "imagem default...";
    self.secureLogotipo = "imagem default segura...";
}

I'm not grasping the async calls concept... can someone help?
