change ajax to this:Add id as key in data to access it in your controller.better add success part for confirmation msg of action.

$.ajax({
             url:'/Teachers/TeachersController/delete/',
                type:'GET',
                data: {id:$(this).attr("href")},
                success:function(resp){//reso is msg string returned from controller.
                    alert(resp);
                  }

            });
