I want to debounce the search input:

```
export class SearchComponent implements OnInit {

    onTextChanged(args) {
        let searchBar = <SearchBar>args.object;

        if (searchBar.text) {
            this.updateResults(searchBar.text);
        } else {
            this.results = new ObservableArray();
        }
    }

    updateResults(q) {
        // hit api
    }
}

<SearchBar (textChange)="onTextChanged($event)"></SearchBar>

```

As is the backend will be hit on every keystroke.
