unable to import procedure

+i8tHi 

I have created a procedure in sql server and successfully added it in my asp.net application using db first approach. 

but after that i have created another procedure in sql server and i am trying again and again to import it in my application by clicking UPDATE MODEL FROM DATABASE

but the new procedure is not importing in application. However in dbcontext file it is adding new procedure reference. but in model new procedure is not adding.

please help me
