Expecting ':' on a click function on IE

I have an ember project which I am testing if IE. It works on chrome and firefox so far but on IE I cant see anything on the page but I get this error

This error points here, right after the word 'click' and before ()

Which looks fine, this code is located in a component. Ive tried passing in the event and returning true but im still getting this error.

Does anyone know whats causing this?
