Ember-Cli Rest-APi Without Adapter

Iam trying to create a Simple Rest-api with out ember data adapter. the problem is , that i can’t make a ajax request with header, i means all request calls with header just stop after prefixer request ( option request).

The Important Thing is That This Reqest Work Fine on Old Ember

app/route/application.js

import Ember from 'ember';
export default Ember.Route.extend({
    model() {
        Ember.$.ajax({
            url: 'url',
            type: "POST",
            headers: { 
                "Accept" : "application/json; charset=utf-8",
                "Content-Type": "application/json; charset=utf-8",
            }
        });
    }
});

but is just call “Option” request, and then nothing happend. this is my option request response
