Set invalid input when it has emojis

I'm trying to set an input as invalid if it contains any emoji (aka emoticons) with a directive.

I'm using the following code: http://codepen.io/fuxes/pen/JYJNKW use 🍻🍹🎂🎊🎉🍸🍰🍻 to start playing.

If I try to use a name such as 🍻🍹🎂🎊🎉🍸🍰🍻 it works fine, it detects that it has emojis. But the weird thing is that if I start to add any letter, it starts to break!

I'll do the following:
🍻🍹🎂🎊🎉🍸🍰🍻asd -> Emojis where detected
🍻🍹🎂🎊🎉🍸🍰🍻asdds -> Emojis where NOT detected
🍻🍹🎂🎊🎉🍸🍰🍻asdd -> Emojis where detected
🍻🍹🎂🎊🎉🍸🍰🍻asdds -> Emojis where detected

Note that 2 and 4 are equals. I don't understand why this behavior happens. Any thoughts?

if you change:

!hasEmojis.test(value)

to:

!value.match(hasEmojis)

I guess something is wrong with your regex or the way you use it, try to first cut it down to 1 or 2 symbols and figure it out and then see if the test method work, or, use the modification I suggested.
