Невозможно расширить страницу редактирования адреса клиента в Magento 2

Question

Я пытаюсь продлить Адрес клиента Редактировать страницу , но она бросает ошибку.Для этого я написал код, как показано ниже.

<Сильный> Composer.json

{
  "name": "learning/module-contact",
  "description": "Contact",
  "require": {
      "php": "~5.5.0|~5.6.0|~7.0.0",
      "magento/framework": "100.0.*",
      "magento/module-ui": "100.0.*",
      "magento/module-config": "100.0.*"
  },
  "type": "magento2-module",
  "version": "1.0.0",
  "license": [
        "OSL-3.0",
        "AFL-3.0"
    ],
  "autoload": {
        "files": [
            "registration.php"
        ],
        "psr-4": {
            "Learning\\Contact\\": ""
        }
    }
}

                $addressCandidatesHtml = $this->getLayout()->createBlock('contact/candidates')->setTemplate('custom.phtml');

                return substr_replace($editHtml, $addressCandidatesHtml, strpos($editHtml, $htmlToInsertAfter)+strlen($htmlToInsertAfter),0);
        }

        return parent::_toHtml();
    }


}

custom.phtml

<h1>Hi I'm here</h1>

ОШИБКА: Object Domdocument должен быть создан

Это правильная процедура для расширения страницы редактирования адреса клиента?
