Not sure this is the place for it (maybe ask on the google group?) But there's two ways:

screen root() { mydiv@<div/> script { mydiv.someplugin(); } }

mydiv will be bound to a JQuery object representing the div. You can also just do this:

screen root() { script { $("#div").someplugin(); } }

So generally your answer is: put it in a script { ... } block.
