title: Issue passing value into Angular 2 component
body: <p>I am trying to pass a simple string into an angular 2 component. For the life of me I can't find the issue. I am passing the value in as a hardcoded value on the component from index.html</p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;
      &lt;title&gt;Angular 2 QuickStart&lt;/title&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
      &lt;link rel="stylesheet" href="styles.css"&gt;
  
      &lt;!-- 1. Load libraries --&gt;
       &lt;!-- Polyfill(s) for older browsers --&gt;
      &lt;script src="node_modules/es6-shim/es6-shim.min.js"&gt;&lt;/script&gt;
  
      &lt;script src="node_modules/zone.js/dist/zone.js"&gt;&lt;/script&gt;
      &lt;script src="node_modules/reflect-metadata/Reflect.js"&gt;&lt;/script&gt;
      &lt;script src="node_modules/systemjs/dist/system.src.js"&gt;&lt;/script&gt;
  
      &lt;!-- 2. Configure SystemJS --&gt;
      &lt;script src="systemjs.config.js"&gt;&lt;/script&gt;
      &lt;script&gt;
        System.import('app').catch(function(err){ console.error(err);  });
      &lt;/script&gt;
    &lt;/head&gt;
  
    &lt;!-- 3. Display the application --&gt;
    &lt;body&gt;
  
  
      &lt;accordian [inputField]="'string'"&gt;Loading...&lt;/accordian&gt;
  
  
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Component</p>
  
  <pre><code>import { Component, Input } from '@angular/core';
  
  @Component({
    selector: 'accordian',
    templateUrl: 'app/accordian.html',
    styleUrls:  ['app/accordian.css']
  })
  export class Accordian {
    @Input() inputField;
    expanded = true;
    expandToggle(){
      console.log(this.inputField)
      this.expanded = !this.expanded;
    }
  }
  </code></pre>
  
  <p>Template</p>
  
  <pre><code>&lt;header (click)="expandToggle($event)"&gt;
    &lt;h4&gt;Select an Activity!!!&lt;/h4&gt;
    &lt;button&gt;{{expanded ? '-' : '+'}}&lt;/button&gt;
  &lt;/header&gt;
  &lt;ul *ngIf="expanded"&gt;
    &lt;li&gt;
        &lt;h5&gt;{{inputField}}&lt;/h5&gt;
        &lt;a href="#"&gt;Update Personal Information&lt;/a&gt;
    &lt;/li&gt;
    &lt;li&gt;
        &lt;h5&gt;User Tools&lt;/h5&gt;
        &lt;a href="#"&gt;Update Personal Information&lt;/a&gt;
    &lt;/li&gt;
    &lt;li&gt;
        &lt;h5&gt;User Tools&lt;/h5&gt;
        &lt;a href="#"&gt;Update Personal Information&lt;/a&gt;
    &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>All I get is undefined when I click on the plus button to spit out the value.
  Any help would be fantastic!</p>
