Please look at line 35 and line 64

Answer 1

I think I have figured this out myself. The way my `oneWayBind` function was set up, it can bind to only one element. I made some changes and now it works.

Also, I discovered `oneWayBind` is actually doing 2-way data binding 😂

Answer 2

<input oninput="app.twoWay=this.value">

Answer 3

Gordon This does not answer my question on WHY the text is not updated.

I actually know about HTML oninput attribute. But it is actually one way binding because if `app.twoWay` changes, the input value will not be updated. So your code is actually not different from the problem I am already facing.
