How is it possible to stop a debounced Rxjs Observable?

I created an observable, which will fire 3 seconds after the last change is made, and calls the publishChange of the service. It works, but I would like to create a doImmediateChange function, which calls publishChange immediately and stops the debounced observable. How is that possible?

My component:

class MyComponent {
    private updateSubject = new Subject<string>();

    ngOnInit() {
        this.updateSubject.pipe(
            debounceTime(3000),
            distinctUntilChanged()
        ).subscribe(val => {
            this.srv.publishChange(val);
        });
    }

    doChange(val: string) {
        this.updateSubject.next(val);
    }

    doImmediateChange(val: string) {

        // Stop the current updateSubject if debounce is in progress and call publish immediately
        // ??
        this.srv.publishChange(val);

    }

}

typeahead.js - Uncaught TypeError: this.displayText(...).toLowerCase is not a function

I've been messing around with typeahead.js templates. No matter what I do, I keep getting the following error:

Uncaught TypeError: this.displayText(...).toLowerCase is not a function in typeahead.min.js:2

My JavaScript looks as following:

$('#search-field').typeahead({
    display: 'value',
    templates: {
        suggestion: function(data) {
            return '<p><strong>' + data.value + '</strong> – ' + data.titleid + '</p>';
        }
    },
    source: function (query, process) {
        return $.get(root + '/api/search.php', { query: query }, function (data) {
            console.log('data:' + data); //outputs the JSON correctly.
            data = $.parseJSON(data);
            return process(data);
        });
    }
});

Where /api/search.php looks like:

[{"value":"Name1","titleid":"Test1"},{"value":"Name2","titleid":"Test2"},{"value":"Name3","titleid":"Test3"}]

I've tried copying code from other examples directly into mine, sometimes even the whole piece, but that didn't solve it either, even though it did work in the example.

How can I solve this, and get the template to work?
