I used the `-e` when running my `app.js` file with nodemon.

```
nodemon app.js -e js,hbs
[nodemon] 2.0.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,hbs
[nodemon] starting `node app.js`

```

But it does not reload after saving any hbs file, no change will occur.
