Dynamically Created Widgets

Can you provide an example on how to dynamically add (and remove) widgets based on a widget event with their own events?
I've looked into using a toggle button event to a function which would toggle between create and destroy of a widget toggleFun :: (MomentIO (Maybe Button) -> MomentIO (Maybe Button))
with accumE (return Nothing) (toggleFun <$ toggleActivateE) with execute but got unexpected results.
How would I remove the event signals when destroying the widget?

Can not bind to #keyPressedEvent

I can not bind to keyPressedEvent of Gtk.Widget. Getting this error:

Couldn't match type `Bool' with `()'
        arising from a use of `signalE1'
    * In a stmt of a 'do' block:
        keyPressE <- signalE1 entry #keyPressEvent

This is due to Handler is defined as type Handler a = a -> IO ()

Is there a way to bind to this event or feed the keys into the network?

Hackage version no longer compatible with recent dependencies

The version published on Hackage has version bounds on reactive-banana (1.2.0.0 is the most recent on Hackage at this time) and the haskell-gi packages (e.g. haskell-gi-base, which is now at 0.21.1, with gi-gtk depending on 0.21.*) that keep it from building against the most recent versions. The cabal file in this repository does not have these bounds, and builds just fine. I've tested it a bit and it seems to work fine, so this might only be a matter of bumping some version bounds and pushing it to Hackage.
