Get JWT Token Created During User profile creation : Ember js

I am using ember-simple-auth and jwt to authenticate a user profile, this is a code for signup and after signing up I wan't to print the token value created(which is in the response) in the console

import Controller from '@ember/controller';

export default Controller.extend({
    actions: {
        signup: function(){
            var credentials = this.getProperties('name','identification','password');
            let list = this.store.createRecord('user', {
                name: credentials.name,
                email: credentials.identification,
                password: credentials.password
            });
            list.save();

        // I want to print the token value in console here

            this.setProperties({
                'name': '',
                'identification': '',
                'password': ''
            });


        }
    }
});
