try this

check this line

                      data:'{"text":"'+groupname+'"}',//put "data:"

now,

$.ajax({
                      type: "POST",
                      contentType: "application/json; charset=utf-8",
                      url: "sample.aspx/getdata",
                      dataType: "json",
                      data:'{"text":"'+groupname+'"}',//put "data:"
                      success: function () {
                         alert("works");
                          // window.location.href = "ClubCreation.aspx";
                      },
                      Error: function () {
                          alert('error');
                      }
                  });

Probabky you missing attributes:

[System.Web.Services.WebMethod()] 
public static void getdata(String text)

Look here for more informations: Using jQuery to directly call ASP.NET AJAX page methods

You have to decorate getdata method with [WebMethod] attribute. In your c# code [WebMethod] is missing.
