Override custom field

Hi, I figured out how to override the action in the controllers.

example

import CreateAccount from 'discourse/controllers/create-account';
export default {

    name: 'Create-Account-Popup',
    initialize: function () {
        CreateAccount.reopen({
            actions: {
                createAccount() {
// my code
                }
            }
        });
}

How to add your @discourseComputed ?

I do as in the example and does not work

export default {
    name: 'Create-Account-Popup',
    
    @discourseComputed()
    ldapForgotPassword() {
        console.log('forgot!!');
        return this.siteSettings.forum_login_popup_use_ldap;
    },
