in your aspx page: 

<asp:HiddenField ID="hdn_checkbox" runat="server" />

in your Javascript:

           function somefunction() {

                $("#<%= hdn_checkbox.ClientID %>").val("test");

            }

            $('.btnGreen').click(function () {

                somefunction();
                alert($("#<%= hdn_checkbox.ClientID %>").val());
                return true;
            });

If you want to get params from the server side, you should use name instead of id attribute.

And your code should work :

$("#elementId").val("value");
