Dynamic Navbar Update Problem

It might be an old question. I have recently created a website where the Navbar menus are dynamically generated by category. Inside those categories, different posts are created from the backend.  Now the problem is when I change the name of the category, it is obvious that the <li> name in the website will also be updated. But it is not happening. Funny part is, it is changing in the database. I already checked that. When I am stopping my project and re-running it again, then it is working. Can anyone help me out with the problem?

 

N:B- I am taking my category name data through a global viewbag filter. 

This is the code.
