doesn't work with ionic 3.9.2

Hi, first thanks for sharing.

I recreated your ionic 3 example on stackblitz to test if it's my fault. But I got there the same error:
`Error: You can applied the "formatterParser" directive only on inputs or elements containing inputs`

https://stackblitz.com/edit/ionic-faeqky?file=pages%2Fhome%2Fhome.html

I think i took all you're code from the example project:
- code from `app.module.ts` to import your module
- code from `home.ts`
- code from `home.html`

Maybe you could have a look at it?
