Computed property on key of object passed as component parameter

I have a messages service that will eventually get messages saved in the database and set them globally for the user but for now I have them set like so

  messages: [
    Ember.Object.create({
      id: 1,
      name: "Out Bid",
      body: "You've been out bid on an item",
      read: false,
      seen: false
    }),
    Ember.Object.create({
      id: 2,
      name: "Out Bid",
      body: "You've been out bid on an item, You've been out bid on an item",
      read: true,
      seen: false
    })
  ],

I have some computed that will tell me how many of these messages have not been marked as seen and when I click on this bubble that shows if that number is over 0 I go to a messages route. In the messages route I inject the messages service and set the model equal to the messages that the service has in it

model() {
    return this.get('messages').get('messages');
}

This route displays the messages in an each loop that renders a component

{{#each model key="id" as |message|}}
    {{message-item message=message}}
{{/each}}

In the component I am trying to add the unread class like so

classNameBindings: ['unread'],
unread: Ember.computed('message.unread',function(){
    return this.get('message').get('read') === false;
}),

And that is working, however when I fire the click action to show the message in a modal and therefore mark it as read the computed is not updating

click() {
    var message = this.get('message');
    this.get('notification').notify({message: message.get('body')});
    message.set('read',true);
}

If I console.log the value of message.get('read') before and after I set it, I see that it is properly being set, but the template is not updating the computed to remove the unread class after it's marked read.

You watch wrong property. Watch read instead of unread:

classNameBindings: ['unread'],
unread: Ember.computed('message.read',function(){
    return this.get('message').get('read') === false;
}),
