Hi, I’m creating a helper that replaces part of a string with an input. Something like this:

`lorem ipsum %s test` =\> `lorem ipsum _______ test`

Then I would like to use that input’s value in other places in the same component.

Here is my helper:

````auto
import Ember from 'ember';

export function replaceInput(params) {
  let phrase = params[0].replace("%s", "<input type='text' value='xxxxxx'/>");
  return new Ember.String.htmlSafe(phrase);
}

export default Ember.Helper.helper(replaceInput);
```
What I need is to be able to type something into the input and retrieve that value as I go.
How would I best go about that?
Thanks for your help!
