Ionic Change Tabs at run time

In my Ionic application , I am using 3 tabs, based on the Web service response I need to add or remove the current showing tabs at runtime. How to achieve this?

Instead of adding or removing tabs, I would suggest enabling and disabling them. That provides a more consistent UX.

Actually I will tell the correct situation . In my ionic Application , there are five tabs are available , but After web service call , based on the response we can remove or adds the tabs dynamically . The changes only applies in the UI , when close the app and Reopen the app . I need changes in the UI instantly , After the Web service call completes ? Could you help me for my problem? can I use location.reload() function ?
