ember-simple-auth custom authorizer is undefined

I have my custom authorizer file that looks like this but is not working,

import Ember from 'ember';
import Base from 'ember-simple-auth/authorizers/base';
export default Base.extend({
    authorize: function(jqXHR, requestOptions) {

    var accessToken = this.get('session.content.secure.token');
    if (this.get('session.isAuthenticated') && !Ember.isEmpty(accessToken)) {
        jqXHR.setRequestHeader('Authorization', 'Bearer ' + accessToken);
    }
}
});

After reviewing this post: http://ift.tt/1VKNt0O it is still not clear to me,here should I call the authorizer?? What about with the session store?? Please can someone can clarify this to me, I'm getting the error authorizer is undefined

my ajax call looks like this:

import Ember from 'ember';
export default Ember.Component.extend({
session: Ember.inject.service(),
gotQuote: false,
quote: "",
actions: {
    getQuote: function() {
            this.get('session').authorize('authorizer:cusmtom', (headerName, headerValue) => { 
            const headers = {};
            headers[headerName] = headerValue;
            var that = this;
            Ember.$.ajax({
                type: 'GET',
                url: 'http://ift.tt/22xjedL',
                headers: headers,
                success: function(response) {
                    that.setProperties({
                        quote: response.quoteText,
                        gotQuote: true
                    });
                },
                error: function(xhr) {
                    alert('Request Status: ' + xhr.status + ' Status Text: ' + xhr.statusText + ' ' + xhr.responseText);
                }
            });
        });
    }
}

});
