Cents not being overwriiten

So I am using your plugin and when I type the numbers everything is getting replaced. Then I use the arrow keys to move before the cents symbol, hit the period and the cursor moves in front of first cent number. Then I try to hit a number and nothing happens.

Here is a link to an Ember Twiddle with an example https://ember-twiddle.com/d7e72b96e9e48b66b4c16988d15a947e?openFiles=routes.application.js%2C

**Update 1:** It appears that bug was introduced in version `0.4.0-beta.2` as when I set it to beta.1, it works
