title: error TS2322: Type 'Event' is not assignable to type 'boolean'
body: <p>I‘m writing a todolist demo.
  When <code>ng serve</code> it, it shows an error:</p>
  <pre><code>Error: src/app/app.component.html:17:58 - error TS2322: Type 'Event' is not assignable to type 'boolean'.
  17  &lt;input class=&quot;toggle&quot; type=&quot;checkbox&quot; [(ngModule)]=&quot;todo.isDone&quot; &gt;
                                                         ~~~~~~~~~~~~~~
  18 
  19  &lt;label&gt;{{ todo.title }}&lt;/label&gt;
     ~~
  </code></pre>
  <p>Also all items not be checked.(even their isDone status is true)</p>
  <p>I def an object in app.component.ts.</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>public todos:{
      id:number,
      title: string,
      isDone: boolean
    }[]=todos
  
  const todos=[
    {
    id:1,
    title:'study',
    isDone:true
  },{
    id:2,
    title:'sleep',
    isDone:true
  },{
    id:3,
    title:'drink',
    isDone:true
  }
  ]</code></pre>
  </div>
  </div>
  </p>
  <p>app.component.html as below.</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;li *ngFor="let todo of todos"&gt;
                  &lt;div class="view"&gt;
                      &lt;input class="toggle" type="checkbox" [(ngModule)]="todo.isDone" &gt;
                      &lt;label&gt;{{ todo.title }}&lt;/label&gt;
                      &lt;button class="destroy"&gt;&lt;/button&gt;
                  &lt;/div&gt;
                  &lt;input class="edit" value="Create a TodoMVC template"&gt;
              &lt;/li&gt;</code></pre>
  </div>
  </div>
  </p>
