## Use

It is common for you to want some data in the template to be available
on an element.  `{{data name}}` allows you to save the
context so it can later be retrieved by [can.data] or
`$.fn.data`. For example,

The template:

    <ul>
      <li id="person" {{data 'person'}}>{{name}}</li>
    </ul>

Rendered with:

    document.body.appendChild(
      can.stache(template,{ person: { name: 'Austin' } });

Retrieve the person data back with:

    $("#person").data("person")
