I try to change title in runtime.But it won't be changed everytime.

[DarrenWorks]

Here is my code.
mBinding.tabs.setOnTabBarSelectedIndexListener(new NavigationTabBar.OnTabBarSelectedIndexListener() {

        @Override
        public void onEndTabSelected(NavigationTabBar.Model model, int index) {
           if (index == 2) {
               model.setTitle("刷新");
           } else {
               mBinding.tabs.getModels().get(2).setTitle("发现");
           }
        }
    });

Thanks for helping.
ASAP
