Update value of a textarea

In order to have 1-way data flow, I'm using a <textarea> element directly instead of the {{textarea}} helper. After I type text into the textarea, though, I'm not able to declaratively update the text!

I can start with a default value, like this:
<textarea>{{name}}</textarea>

As long as I don't type into the textarea, I can change the "name" property and it will update the textarea text automatically.
Once I type into the textarea, though, the textarea doesn't get updated when I change the "name" property.

I suspect this is because of the JavaScript "value" property on the textarea, but this same exercise works with an input tag. Any ideas of how to keep 1-way data flow but get this to work? I could probably change the JavaScript value property of the textarea when the property changes, but that feels like I'm forcing it when it should just update.
