Plunkr Case (Bug Reports)
No need for PlunkR Case: just go on PrimeNG Demo page about editor (toolbar Editor):

https://www.primefaces.org/primeng/#/editor

Current behavior
Using the editor, you can see dirty/pristine state changes on p-editor element when you type something inside.

BUT touhed/untouched state doesn't change and remain untouched.

Expected behavior
We expect that going, and typing in the p-editor trigger a touched/untouched state change

Minimal reproduction of the problem with instructions
Just load the <p-editor> module. Go in the editor and type something: you will see ng-untouched class and state remains here and ng-touched is never triggered.

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 4.0.2 (also tested on 4.0.1)

• PrimeNG version: 4.0.0-rc.3

• Browser: All I was able to test on (IE, Edge, Firefox last version, Chrome last version)

• Language: TS
