Vaadin 8 Grid filtering

Hi, 

I'm trying to do Grid filters for columns with Vaadin 8 like: http://demo.vaadin.com/book-examples-vaadin7/book/#component.grid.filtering

But there isn't methods anymore like: 
Grid.getContainerDataSource() or TextField.addTextChangeListener in Vaadin 8 (but those are in Vaadin 7). 

Any help to find a new example for Vaadin8 (Google really didn't gave any) ? or advice how to get the filtering in grid working.

In Vaadin 8 Grids data model is no longer container, but DataProvider instead. Here is the interface spec for the ConfigurableFilterDataProvider.

https://vaadin.com/api/8.0.5/com/vaadin/data/provider/ConfigurableFilterDataProvider.html

ListDataProvider implements this interface, further specs about using filtering is found here:
