Question posted in 
my problem is to, when open with my index.cshtml(Asp.net MVC) in visual studio(2017), run the project that time JavaScript and jQuery function working properly but after close that index.cshtml page again runs the same thing, that time JavaScript and jQuery function not working. I find out those things put the breakpoints in my controller. The purpose of the javascript, jQuery and ajax function is to if I choose the item name from the dropdown list that time price(inside the text box) should come automatically according to the item name.
here I show my code
Index.cshtml
@model dynamic
@{
ViewBag.Title = "Index";
}

remove your all script files and re-install the script package using Nu-Get package.sometime it will work for you.
I think your index.cshtml not loading completely.can you check the url while script working time and not working time? Also, compare those things with Routeconfig.cs as well.
