Ember CLI - Custom DS.LSAdapter.extend returns undefined - ember-data

Question

I want to save claims in localstorage with a custom LSAdapter.
The app/adapters folder has two adapters: application.js and claim.js. After login I want to save de retrieved claims in de store, like this:
claimarr.forEach(function(claimString){
var claimsplitted = claimString.split(" ");
var record = store.createRecord('claim',
{
'type' : claimsplitted[0],
'value': claimsplitted[1]
}
);
record.save();
});
I am not able to create the custom LSAdapter. I am using Simple Auth, and the addon writes data to localStorage!
adapters/application.js
import DS from "ember-data";
export default DS.RESTAdapter.reopen({
namespace: 'api/',
host: 'http://localhost:1336',
headers: function() {
return {
"Access-Control-Allow-Origin": "*",
"Content-Type": "application/json"
};
}.property().volatile()
});
adapters/claim.js
import DS from "ember-data";
export default DS.LSAdapter.extend({
namespace: 'api/'
}
);
Brocfile.js
..
app.import("bower_components/ember-localstorage-adapter/localstorage_adapter.js");
module.exports = app.toTree();
models/claim.js
import DS from "ember-data";
export default DS.Model.extend({
type : DS.attr('string'),
value : DS.attr('string'),
});
UPDATE
Workaround in my logincontroller:
controllers/login.js
actions: {
login: function(){
//this.set('currentDate', moment());
//var now = moment;
//console.log(this.now);
var self = this;
self.set('errorMessage', null);
this.get('session').authenticate(this.authenticator, {
identification: this.get('identification'),
password: this.get('password')
})
.then(
function() {
function getClaimSet(session){
var claimSet = [];
//build claimSet from base64 string
var claimarr = window.atob(session.content.claims).split(",");
claimarr.forEach(function(claimString){
var claimsplitted = claimString.split(" ");
var record =
{
'type' : claimsplitted[0],
'value': claimsplitted[1]
};
claimSet.push(record);
});
return claimSet;
}
var session = self.get('session');
var claimSet = getClaimSet(session);
session.set("claimSet" , claimSet );
session["hasClaim"] = function(value, type){
if(typeof(type) === "undefined"){
type = "Method";
}
var foundArr = session.content.claimSet.filter(function(claim){return claim.type === type && claim.value === value;});
return foundArr.length > 0;
};
I'm now able to use: session.hasClaim(value, type)
