title: ember {{input}} helper not working
body: <p>I can't for the life of me figure out why this won't work. Maybe it's obvious, but I've been staring at it too long.</p>
  
  <p>I want the {{input}} pre-populated with the value of Title, the label gets filled in correctly...</p>
  
  <pre><code>    &lt;ul&gt;
        {{#each}}
          &lt;li&gt;
          {{input type="text" value=Title }}
            &lt;label&gt;{{Title}}&lt;/label&gt;
          &lt;/li&gt;
        {{/each}}
      &lt;/ul&gt;
