I'm not a java expert but I solve your problem like this:

@FunctionalInterface
public interface AutoCompleteCallable {
  String call(T model) throws Exception;
}

I define the parameter in my special Interface

public  void initialize(List entries, AutoCompleteCallable getSearchText) {.......
//call here
String value = getSearchText.call(item);
...
}

Finally, I implement getSearchText method while calling initialize method.

initialize(getMessageContactModelList(), new AutoCompleteCallable() {
          @Override
          public String call(Object model) throws Exception {
            return "custom string" + ((xxxModel)model.getTitle());
          }
        })
