I am having trouble viewing a Form View in a new page.

I am implementing a backend  app drawer with tabs. One Tab should view a user preferences.

I am doing JS and XML template
I did AppDrawer in JS as follow

var AppDrawer = Widget.extend({......        This is working fine

Now Making new widget for user preference 
var Preferences = Widget.extend({
    init: function() {
        this._super.apply(this, arguments);
        this.$el = $('a[href="#Preferences"]');
        How to view base.view_users_form_simple Form View or base.action_res_users
