How to prevent clearing my password when login form is submitted?

Question

I'm using the basic configuration of ember-simple-auth. When I click submit, request is gone to backend but my password field becomes empty. My username field is still filled.

My template: login.emblem

form.submit='authenticate'
  Ember.TextField id='identification' valueBinding='identification'
  Ember.TextField id='password' type='password' valueBinding='password'

  button type='submit'
    | Login

Controller: login.js

import Ember from "ember";
import LoginControllerMixin from 'simple-auth/mixins/login-controller-mixin';
export default Ember.Controller.extend(LoginControllerMixin, {
  authenticator: "simple-auth-authenticator:oauth2-password-grant",
});

Route: login.js

import Ember from "ember";
import UnauthenticatedRouteMixin from 'simple-auth/mixins/unauthenticated-route-mixin';
 export default Ember.Route.extend(UnauthenticatedRouteMixin, {
});

Instead of using LoginControllerMixin's authenticate action you can simply define your own:

import Ember from 'ember';
import AuthenticationControllerMixin from 'simple-auth/Authentication-controller-mixin';

export default Ember.Controller.extend(AuthenticationControllerMixin, {
  authenticator: 'simple-auth-authenticator:oauth2-password-grant',
  actions: {
    authenticate: function() {
      var data = this.getProperties('identification', 'password');
      return this._super(data);
    }
  }
});
