Ionic 2 Conference app & Angular translate expression

In the app.component of the Ionic 2 Conference app I am trying to apply a language switch for the sidemenu links.

As you will see in this code, from line 44 the titles are already contained in {{}} expressions, and I can’t seem to find away to apply the angularTranslate:

{{‘SCHEDULE’ | translate }}

as they are already included in expressions. I need a workaround for this, can someone give me the solution? You will see in line 23 that the:

title: string;

Would changes need to made here too, and how? Thanks in advance.
