How to serialize ember paginated data

Hi i am getting following json from my rest API.

{
  "content": 
  [{
     "id" : 56789,
     "name" : "sample book",
     "status": "available",
 },{
     "id" : 56789,
     "name" : "sample book",
     "status": "available",
 }],
     "last": true,
     "totalElements": 5,
     "totalPages": 2,
     "size": 3,
     "number": 1,
     "sort": null,
     "first": false,
     "numberOfElements": 2
 }

Ember Book Model

export default DS.Model.extend({
  id: DS.attr(),
  name: DS.attr(),
  status: DS.attr()
});

Ember Route

import Ember from 'ember';
import RouteMixin from 'ember-cli-pagination/remote/route-mixin';

export default Ember.Route.extend(RouteMixin, {

model: function(params) {
     params.paramMapping = {
     perPage: "size"};
     return this.findPaged('book',params);
}
});

In the Firefox network tab i can able to see the response but in browser console i am getting the following message,

Error while processing route: book.index data is undefined _pushInternalModel

In Chrome getting following exception:

ember.debug.js:30610 Error while processing route: books.index Cannot read property 'type' of undefined TypeError: Cannot read property 'type' of undefined

I am using following versions of ember : "ember-cli": "2.5.0", "ember-cli-pagination": "2.2.2"

I am new to ember.Could anyone please help me to resolve this issue?I think i should serialize the response using "normalizeResponse" but i don't know how to do it.
