Following the reactivex docs, you should also subscribe to the pipe observable :

.pipe(
    debounceTime(500),
    distinctUntilChanged(),
    map((val) => {
        ...
    })
)
.subscribe();

An Observable is called a “cold” Observable if it does not begin to emit items until an observer has subscribed to it.
