Emitting events with Bacon.js

I'm learning Bacon.js and I'm very confused as to how I'm supposed to emit events.

I have a super-simple example here of events in node.js

var events = require('events')
var eventEmitter = new events.EventEmitter()

eventEmitter.on("add", function(data){
  console.log(data+1)
  return data+1
})

eventEmitter.emit('add', 5)
eventEmitter.emit('add', 3)

setTimeout(function(){
  eventEmitter.emit('add', 13)
}, 1000)

setTimeout(function(){
  eventEmitter.emit('add', 10)
}, 3000)

I can't find one example of how something simple like this would be done with BaconJS and node.

I tried this:

var add = Bacon.fromEvent(eventEmitter, "add")

add.onValue(function(data){
  return data+1
})

add.map(5)
add.map(3)
add.map(13)
add.map(10)
