ControlsFX: AutoCompletion bind to a model class

Question

I have a model class:

public class Client {
    private long id;
    private String name;


    @Override
    public String toString() {

        return this.name;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

and I have a Textfield that I want to use auto complete using a list of Client class, using ControlsFX, here is what I did:

AutoCompletionBinding<Client> binding = TextFields.bindAutoCompletion(searchField, SuggestionProvider.create(appState.clients));

Where appStat.Clients is a list of Client class. For some reason I get no suggestions appearing. What am I doing wrong?
