[angular] How can I use/create dynamic template to compile dynamic Component with Angular 2.0?

I decided to compact everything I learned into one file. There's a lot to take in here especially compared to before RC5. Note that this source file includes the AppModule and AppComponent.

import {
  Component, Input, ReflectiveInjector, ViewContainerRef, Compiler, NgModule, ModuleWithComponentFactories,
  OnInit, ViewChild
} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';

@Component({
  selector: 'app-dynamic',
  template: '<h4>Dynamic Components</h4><br>'
})
export class DynamicComponentRenderer implements OnInit {

  factory: ModuleWithComponentFactories<DynamicModule>;

  constructor(private vcRef: ViewContainerRef, private compiler: Compiler) { }

  ngOnInit() {
    if (!this.factory) {
      const dynamicComponents = {
        sayName1: {comp: SayNameComponent, inputs: {name: 'Andrew Wiles'}},
        sayAge1: {comp: SayAgeComponent, inputs: {age: 30}},
        sayName2: {comp: SayNameComponent, inputs: {name: 'Richard Taylor'}},
        sayAge2: {comp: SayAgeComponent, inputs: {age: 25}}};
      this.compiler.compileModuleAndAllComponentsAsync(DynamicModule)
        .then((moduleWithComponentFactories: ModuleWithComponentFactories<DynamicModule>) => {
          this.factory = moduleWithComponentFactories;
          Object.keys(dynamicComponents).forEach(k => {
            this.add(dynamicComponents[k]);
          })
        });
    }
  }

  addNewName(value: string) {
    this.add({comp: SayNameComponent, inputs: {name: value}})
  }

  addNewAge(value: number) {
    this.add({comp: SayAgeComponent, inputs: {age: value}})
  }

  add(comp: any) {
    const compFactory = this.factory.componentFactories.find(x => x.componentType === comp.comp);
    // If we don't want to hold a reference to the component type, we can also say: const compFactory = this.factory.componentFactories.find(x => x.selector === 'my-component-selector');
    const injector = ReflectiveInjector.fromResolvedProviders([], this.vcRef.parentInjector);
    const cmpRef = this.vcRef.createComponent(compFactory, this.vcRef.length, injector, []);
    Object.keys(comp.inputs).forEach(i => cmpRef.instance[i] = comp.inputs[i]);
  }
}

@Component({
  selector: 'app-age',
  template: '<div>My age is {{age}}!</div>'
})
class SayAgeComponent {
  @Input() public age: number;
};

@Component({
  selector: 'app-name',
  template: '<div>My name is {{name}}!</div>'
})
class SayNameComponent {
  @Input() public name: string;
};

@NgModule({
  imports: [BrowserModule],
  declarations: [SayAgeComponent, SayNameComponent]
})
class DynamicModule {}

@Component({
  selector: 'app-root',
  template: `
        <h3>{{message}}</h3>
        <app-dynamic #ad></app-dynamic>
        <br>
        <input #name type="text" placeholder="name">
        <button (click)="ad.addNewName(name.value)">Add Name</button>
        <br>
        <input #age type="number" placeholder="age">
        <button (click)="ad.addNewAge(age.value)">Add Age</button>
    `,
})
export class AppComponent {
  message = 'this is app component';
  @ViewChild(DynamicComponentRenderer) dcr;

}

@NgModule({
  imports: [BrowserModule],
  declarations: [AppComponent, DynamicComponentRenderer],
  bootstrap: [AppComponent]
})
export class AppModule {}`
