title: "Tag start is not closed" when using Handlebars.js
body: <p>I'm getting an error that says "Tag start is not closed" in the following HTML code after the input tag. I can't seem to figure out why since I am using the Handlebars syntax properly. Can someone help me out please?:</p>
  
  <pre><code>&lt;!DOCTYPE HTML&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;Title&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;div id="todo"&gt;
      &lt;/div&gt;
      &lt;script id="item-template" type="text/x-handlebars-template"&gt;
          // Your code goes here
          &lt;div&gt;
              &lt;input id="todo-complete" type="checkbox" {{#if completed}} "checked" {{/if}}&gt;
              &lt;label&gt;{{title}}&lt;/label&gt;
          &lt;/div&gt;
      &lt;/script&gt;
  
  
      &lt;script src= "underscore.js"&gt; &lt;/script&gt;
      &lt;script src="handlebars-v1.3.0.js"&gt; &lt;/script&gt;
      &lt;script src="backbone.js"&gt; &lt;/script&gt;
      &lt;script src="jquery-1.11.1.js"&gt; &lt;/script&gt;
      &lt;script src="main.js"&gt; &lt;/script&gt;
  &lt;/body&gt;
  </code></pre>
