This is coming a bit late, just for clarification anyways. This is how you can create a simple observable in case you want to mimic your own like promise. You do

let observable=Observable.create(observer => {
      setTimeout(() => {
        observer.next("data to send can be object or anything");
        console.log("am done");
        observer.complete(); // to show we are done with our processing
       // observer.error(new Error("error message"));
      }, 2000);

    })

to subscribe to it is very easy

observable.subscribe((data) => {
console.log(data); // should be 'data to send can be object or anything'
});

you can also convert it to promise using toPromise() or fromPromise(observable) operator and so on.
