title: handlebars: Pass dynamic variables to partials
body: <p>I have a partial that contains the common structure of my web page:</p>
  
  <pre><code>&lt;script id="page-template" type="text/x-handlebars-template"&gt;
      .....
      &lt;div class="page-content"&gt;
          &lt;div class="page-header"&gt;
              &lt;h1&gt;{{title}}
                  &lt;small&gt;
                      &lt;i class="ace-icon fa fa-angle-double-right"&gt;&lt;/i&gt; {{subtitle}}
                  &lt;/small&gt;
                  {{/if}}
              &lt;/h1&gt;
          &lt;/div&gt;
          ......
      &lt;/div&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>Then, from each page, I call the partial passing the attributes <strong>title</strong> and <strong>subtitle</strong>. It works fine with constants attributes, for instance:</p>
  
  <pre><code>{{#&gt; page title="Customers" subtitle="List of customers"}}
    &lt;!-- Page HTML --&gt;
  {{/page}}
  </code></pre>
  
  <p>However, it doesn't work when I try to pass a variable:</p>
  
  <pre><code>{{#&gt; page title="Customer" subtitle="{{customer.name"}}
    &lt;!-- Page HTML --&gt;
  {{/page}}
  </code></pre>
  
  <p>It displays {{customer.name}} instead of the real name of the customer. Is it possible to make this work?</p>
  
  <p>Thanks in advance!</p>
