サブチャイルドコンポーネントへのAngularJS 2依存性注入

Question

角度のある素材に似たカードコンポーネントを作成しようとしています。それぞれのカードに[title]依存関係の注入をするのに問題がある以外は、すべてが完全に機能しています。ここで

が私のコードです：

TitleDirective

import { Directive, Input, HostListener } from '@angular/core'; 

@Directive({ 
    selector: '[title]' 
}) 

export class TitleDirective { 
    private _defaultTitle = ''; 

    @Input('title') title: string; 

    @HostListener('mouseenter') onMouseEnter() { 
     console.log('hhh'); 
     console.log(this.title); 
    } 
} 

CardItemComponent

import { Component } from '@angular/core'; 

import { TitleDirective } from '../title.directive'; 

@Component({ 
    selector: 'card-item', 
    templateUrl: 'app/directive/cards/card-item.component.html', 
    directives: [ 
     TitleDirective 
    ] 
}) 

export class CardItemComponent { } 

HTMLページ

<mc-cards> 
    <mc-card> 
     <mc-card-header> 
      <mc-button>LEFT</mc-button> 
      <span flex></span> 
      <h1>Title 1</h1> 
      <span flex></span> 
      <mc-button>RIGHT</mc-button> 
     </mc-card-header> 
     <mc-card-body> 
      <mc-card-item [title]="Hello"> 
        <p> 
         Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. 

         The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
