I think you have to use the rendering callback here... osmething like:
onMouseOver: (html
updater id: 'previewId'; "the div id that will be redraw
with the rendering callback associated here "
triggerFormElement: 'attributePreview'); "trigger the action
associated to the form element 'attributePreview' callback
callback: [:renderer | "some optional actions" . self
renderUpdateAttributePreviewOn: renderer])

Just search for senders of #updater and see examples. If you have a
squeak-web image, there should be plenty.
