Javafx CheckedListView duplicated elements

I have one listView and one checked ListView which need to interact with each other. Photo

When i select an element from listView, checked ListView should show me checked items (in one method) and be able to add or remove elements(another method).

//Method_One

protected void methodOne() {
    listView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Role>() {
        @Override
        public void changed(ObservableValue<? extends Role> observable, Role oldValue, Role newValue) {
            r = newValue;
            Query query = jpa.getEntityManager().createQuery("SELECT v FROM Views v WHERE v.idRole =:idRole");
            query.setParameter("idRole", r);
            List rez = query.getResultList();
            checkedListView.getCheckModel().clearChecks();
            Iterator<Views> it_view = rez.iterator();
            while (it_view.hasNext()) {
                Views v = it_view.next();
                int i = v.getIdViews();
                checkedListView.getCheckModel().check(i - 2);
            }
        }
    });

}

//Method_Two

private void methodTwo() {
    checkedListView.getCheckModel().getCheckedItems().addListener(new ListChangeListener<Views>() {

        @Override
        public void onChanged(ListChangeListener.Change<? extends Views> c) {
            c.next();  
            if (c.wasAdded()) { 
                System.out.println("Item Checked : " + c.getAddedSubList().get(0));

            } else if (c.wasRemoved()) {
                System.out.println("Item Unchecked : " + c.getRemoved().get(0));
            }
        }
    });
}

Problem is when i select an element on ListView it addes duplicated elements of checkedListView.
