title: jquery get children by attribute
body: <p>This code is returning an empty array when I run it even though there is a div with the attribute [data-directory] in the container.</p>
  
  <p><code>$(container).children( '[data-directory]' )</code></p>
  
  <p>container is valid, and the children are there when I log $(container), I'm not sure why it isn't pulling the child that is there though.</p>
