Ensure That jQuery Is Working

Firstly, ensure that your jQuery code is working properly and is referenced. You'll need to include a reference to the library prior to calling any jQuery-related code :

If you want to perform a GET...

You are specifying within your ajax() call that you are making a POST request via the type attribute, but your Controller Action is explicitly expecting a GET via the [HttpGet] attribute decorating your action.

You can resolve this by changing your type attribute from POST to GET (or you could remove it entirely as GET is the default):

type: "GET",

If you want to perform a POST...

Alternatively, if you want to actually perform a POST, then just keep your existing code and use the [HttpPost] attribute instead :

[HttpPost]
public ActionResult Remove(int? Book_id)
{
     // Code omitted for brevity
}
