如何将对象的属性绑定到 Angular 中的另一个对象内部？

Question

I'm trying to bind a string object property it is inside an object via input field, but when I write inside it, it will return "Cannot read property 'key1' of undefined".

Change Text object from

text: test = {};

to

text: test = {
    obj1: {
      
    }
  };

Because for a key it can create when value is entered, but for a object like obj1, you need to defined it for accessing any key.
