Problems using "| translate" filter

I just tried to use your i18n package and if I use $t('hello world') it works fine, but when I try to use {{ 'hello world' | translate }} I get this error message:

Error in render function: "TypeError: Cannot read property '$t' of undefined"

You can find my package.js and all other related files here: https://github.com/signdict/website/tree/add-webcam-capture-code

If there is anything I can do to help debug this, say what you need and I will try to deliver it.
