Angular 2 - Passing an argument to a custom pipe

Question

I have a created a pipe which can receive 2 arugments, but I'm not sure how I can sent them.

here's my pipe:

export class TranslationPipe implements PipeTransform {

    private capitalize: boolean;

    constructor(
        private translationService: TranslationService
    ) {
        this.capitalize = true;
    }

    transform(key: string, capitalize?: boolean): string {
        if (typeof capitalize !== "undefined" || capitalize !== null)
            this.capitalize = capitalize;

        return this.translationService.getTranslation(key, this.capitalize);
    }
}

and here is my HTML

{{ 'searchquery' | translate }}

this works, but how can I pass capitlize = false aswell? I've tried some googling but I can't really find any example the way I want to implement it (maybe I'm doing it wrong?)

thanks for your help!

{{ 'searchquery' | translate:false }}

{{ 'searchquery' | translate:'toUsEn' }}
