handlebars helper's parameter is not bound

<span class="badge badge-inverse">{{kudosReceivedNum user.kudoReceiveds}}</span>

Ember.Handlebars.registerBoundHelper 'kudosReceivedNum', (kudos, options) ->
  kudosTotal = 0
  if kudos
    kudos.forEach (item) ->
      kudosTotal += item.get 'value'

    kudosTotal

ApplicationRoute:

newKudo = Sks.KudoReceived.createRecord value: kudoNum, comment: kudoComment
user.get('kudoReceiveds').pushObject(newKudo)

It only works when I do a refresh or go from another view.

Bound helpers actually take an additional option which are additional dependent keys. For arrays you need to specify @each as a dependency. Off the top of my head this would look like:

Ember.Handlebars.registerBoundHelper 'kudosReceivedNum', ((kudos, options) ->
  kudosTotal = 0
  if kudos
    kudos.forEach (item) ->
      kudosTotal += item.get 'value'

    kudosTotal), '@each'
