No FileField Insert options when uploading an image

Hi!

I've added created a new FileField in a custom content type, and checked the "HTML Insert" option and also selected some ImageCache presets.
I navigate to the node/mycustomctype/add and load an image. Now, not sure if this is a bug report, but when I upload an image no
"Send to textarea" button appear. The ImageCache presets doesn't appear there either.

I've tried to debug the problem, and successfully come to the conclusion that this...

  // Add the insert widget, replacing the 'filefield-insert-location' element.
  $('div.filefield-element', context).each(function() {
    if ($(this).find('input[name$="[fid]"]').val() > 0) {
      var widget = $('input.filefield-insert-widget', this).val();
      var $location = $('input.filefield-insert-location:first', this);
      var $insert = $(Drupal.settings.fileFieldInsert.widgets[widget]).find('input.filefield-insert').click(fileFieldInsert).end();
      $location.replaceWith($insert);
    }
  });

...code in filefield_insert.js is never executed.

Any ideas?
