Type: object
An object where the keys represent keys in your object and the values are the listen functions from a weakmap-event.
Type: function
Arguments: state, data
An optional function called with the state and event data. By default, the event data is forwarded up. By passing in a function, you can add or remove properties or return entirely different data.
If you return false, the listeners will not be called.
