this.node is already a jQuery node, so no need to use $(this.node).

(In the past is was a DOMElement, so this WAS necessary.)

Omitting the $(...) call means that the Reference Universe widget is
no longer dependent on our old $ object still being so named, so that
it will work in contexts where another library redefines $. (That's
not a hypothetical: Wolfram saw this happen in his work embeddeding
widgets in Koha.)
