Fix fugue not working when implement in multiple dom

[junhuif]

<h2>Create a new address</h2>
<form id="new-address">
  <input type="text" name="address">
  <button type="submit"></button>
</form>

<h2>Edit address</h2>
<form id="edit-address">
  <input type="text" name="address">
  <input type="hidden" name="id" value="1">
  <button type="submit"></button>
</form>

$("#new-address, #edit-address").fugue({
  done: function() {
    // blabla
  }
})

As above example shows, the fugue will implement to #new-address form, but not working in #edit-address.
