Best practice for input debounce (no-noncallable-event-binding)

Today I see this code:

<img width="883" alt="Screenshot 2019-11-12 at 19 20 38" src="https://user-images.githubusercontent.com/1007051/68698603-92cc3d00-0581-11ea-9927-6e7624be941e.png">

And the [`debounce`](https://lodash.com/docs/4.17.15#debounce) function is from `lodash-es`:

```javascript
import { debounce } from 'lodash-es';
```

The code works, but `lit-analyzer` complains.
