findAll events with ember-data

I'm very new in Ember world, and I'm struggling myself to make ember data work, but errors always happen.

I want get all my events with this.findAll('events'); in my events route, i already setup everything right i think.. but still not working.

Currently two errors is appearing.

1:

WARNING: Encountered "data" in payload, but no model was found for model name "datum" (resolved model name using SiteApp.ApplicationSerializer.modelNameFromPayloadKey("data"))

2:

Error while processing route: events Assertion Failed: You must include an 'id' for undefined in an object passed to 'push' Error: Assertion Failed: You must include an 'id' for undefined in an object passed to 'push'

I'm not getting where i'm messing up.

This is all i have:

Ember initialization.

window.SiteApp = Ember.Application.create({
  LOG_TRANSITIONS: true
});

Configuration of RestAdapter and RestSerializer:

SiteApp.ApplicationAdapter    = DS.RESTAdapter.extend({
  namespace: 'api
});
SiteApp.ApplicationSerializer = DS.RESTSerializer.extend({
  primaryKey: '_id'
});

Events router:

SiteApp.EventsRoute = Ember.Route.extend({
  model: function() {
    this.store.findAll('events');
  }
});

Events model:

SiteApp.Events = DS.Model.extend({
  _id         : DS.attr(),
  date        : DS.attr(),
  description : DS.attr(),
  hiw         : DS.attr(),
  hour        : DS.attr(),
  meeting     : DS.attr(),
  men         : DS.attr(),
  name        : DS.attr(),
  title       : DS.attr(),
  women       : DS.attr(),
  created_at  : DS.attr(),
  is_active   : DS.attr(),
  updated_at  : DS.attr()
});

So, when i access the route /api/events, this is the JSON format that i'm going receive:

{
  data: [{
    _id: "55f660bdd80a0fd2e298f333",
    title: "Pubx",
    date: "2015-09-05T03:00:00.000Z",
    created_at: "2015-09-14T05:53:01.292Z",
    __v: 0,
    updated_at: "2015-09-14T13:34:52.780Z"
  }, {
    _id: "55f660bdd80a0fd2e298f335",
    title: "Pub",
    date: "2015-09-05T03:00:00.000Z",
    created_at: "2015-09-14T05:53:01.610Z",
    __v: 0
  }, {
    _id: "55f660bdd80a0fd2e298f336",
    title: "Pub",
    date: "2015-09-05T03:00:00.000Z",
    created_at: "2015-09-14T05:53:01.769Z",
    __v: 0
  }, {
    _id: "55f660bdd80a0fd2e298f337",
    title: "Pub",
    date: "2015-09-05T03:00:00.000Z",
    created_at: "2015-09-14T05:53:01.943Z",
    __v: 0
  }, {
    _id: "55f6cc55f8aeb32de86a88e9",
    date: "2015-09-15T00:00:00.000Z",
    created_at: "2015-09-14T13:32:05.477Z",
    __v: 0
  }]
}

I already search a lot and i just cant figure out what is the problem here, i'm not seeing where is the problem.. :/

Thanks very much!
