How does ngSwitch work in Angular2?

Question

I am trying to use ngSwitch as in this example but I get an error:

My Component:

  template: `     <div layout="column" layout-align="center center">       <div [ng-switch]="value">        <div *ng-switch-when="'init'">      <button md-raised-button class="md-raised md-primary">User</button>      <button md-raised-button class="md-raised md-primary">Non user</button>       </div>   <div *ng-switch-when="0">Second template</div>   <div *ng-switch-when="1">Third Template</div> </div>   </div>`,     directives: [NgSwitch, NgSwitchWhen, NgSwitchDefault]  }) 

My plunker - wizard.ts

What did I miss? Thank you

Working Demo. you can check browser's console

changed ng-switch to ngSwitch
changed ng-switch-when to ngSwitchWhen

<div layout="column" layout-align="center center">         <div [ngSwitch]="value">       <div *ngSwitchWhen="'init'">          <button md-raised-button class="md-raised md-primary">User</button>          <button md-raised-button class="md-raised md-primary">Non user</button>        </div>       <div *ngSwitchWhen="0">Second template</div>       <div *ngSwitchWhen="1">Third Template</div>     </div>  </div>    <button md-fab  class="md-fab wizard_button--next"   aria-label="about"   (click)="onNext()"> <i class="material-icons" md-icon="">play_arrow</i>  </button>
