如何在 oc 2.0 的自定义模块中自动初始化变量

Question

最近我开始为 opencart 2 开发自定义模块，在一个模块中我需要用户可以增加（添加）和减少（minus/hide）文本字段。我必须使用 jQuery 来执行此操作。在这里您可以找到演示：

http://demo.themextension.com/admin

在 extensions/modules 菜单标题旋转器内容下

所以问题是当我保存它并再次打开时它没有显示使用 jQuery 创建的其他字段。

.tpl 文件

http://pastebin.com/Fs6t2T8j

控制器文件

http://pastebin.com/KF5DG4Ay

所以我不知道如何管理 tpl 文件中的自定义字段

如有任何帮助，我们将不胜感激。谢谢
