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

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
