jQuery validation plugin is not working in MVC 5

Question

I have made a form to insert some data into database using MVC 5. When I'm using the Layout page in the view , my jQuery validations are not firing. But when I'm not using the Layout page , the jQuery validations are firing.

I have used the same validation code in both cases.

Validation works well in this code: https://pastebin.com/ehyuL38L

 

But validation does not work here :
