Simple Angular 2 Forms with Firebase

index.ts

import {bootstrap, Component, Decorator, View, If, For, EventEmitter} from 'angular2/angular2';
import {FormBuilder, Validators, FormDirectives, ControlGroup} from 'angular2/forms';

@Component({
  selector: 'app',
  injectables: [FormBuilder]
})
@View({
  template: `
  <div class="container" [control-group]="myForm">
    <h2>Simple Form</h2>
    <div class="form-group"
         [class.has-success]="myForm.controls.name.valid"
         [class.has-error]="! myForm.controls.name.valid"
    >

      <label class="control-label">Name</label>
      <input control="name" class="form-control">

    </div>

    <div class="form-group"
         [class.has-success]="myForm.controls.age.valid"
         [class.has-error]="! myForm.controls.age.valid"
    >

      <label class="control-label">Age</label>
      <input type="number" control="name" class="form-control">

    </div>

  </div>
  `,
  directives: [FormDirectives]
})
class AppComponent {
  myForm:ControlGroup;
  builder:FormBuilder;

  constructor(b:FormBuilder) {
    this.builder = b;

    this.myForm = b.group({
      name: ["", Validators.required], // required
      age: [""] // optional
    });

    this.ref = new Firebase('https://ngforms.firebaseio.com/form');

    // save changes to Firebase as the form updates
    this.myForm.valueChanges.subscribe(function(value) {
      this.ref.set(value);
    }.bind(this));
  }
}

export function main() {
  bootstrap(AppComponent);
}

You can also use https://github.com/gngeorgiev/firesync. It does not depend on a framework so it should work nicely with angular2.

I'm getting crazy with that!!! I'm new on angular and firebase too, so i'm suffering to populate my forms with read data from firebase promise. Yes, I´m suffering too to understand how to deal with promises vs observables.
I will apreciate any help.
