this is my complete code working very fine, ill be using this in the future a lot in my projects. this is basics in net programming imo so im posting it here. (damn editing posts here slows down firefox like hell. no code insert button?)

client side:

AutoPostBack="false"
onclick=<%# String.Format("onCheckedLevelClientClick(this, '{0}')", Eval("anQId"))%>
Checked='<%# (Eval("checkedLevel2").GetHashCode() = 1)%>' />

 function onCheckedLevelClientClick (checkbox, anQId)
       {
       sendAjaxRequest($(checkbox), { 'FUNCTION': 'saveOneCheckedCheckboxAjax', 'param0': anQId, 'param1': checkbox.checked });               
   }

   function sendAjaxRequest(htmlEl, jsonData) {
       jQuery.ajax({
           type: "POST",
           async: "false",
           url: location.href,
           dataType: "text",
           data: (jsonData),
           success: function (data) {
               dynNotifyEl(htmlEl, undefined, "Shranjeno", undefined);
           },
           error: function (XMLHttpRequest, textStatus, errorThrown) {
               dynNotifyEl(htmlEl, undefined, undefined, 'Napaka: ' + textStatus + ', ' + errorThrown);
           },
           beforeSend: function (xhr) {
               xhr.setRequestHeader("X-OFFICIAL-REQUEST-MINE", "TRUE");//Used to ID as a AJAX Request
               dynNotifyEl(htmlEl, "", undefined, undefined);
           },
           complete: function (XMLHttpRequest, textStatus) {
           }
       });
   }

            // create dynamic notification element
   // all arguments are optional except targetEl
   function dynNotifyEl(targetEl, waitMsg, saveMsg, errorMsg)
   {        
       var type = 0;
       var dynElExisting = targetEl.siblings(".notifyDiv");
       if (dynElExisting.length)
           dynElExisting.remove();        
       var dynEl;
       if (typeof errorMsg !== 'undefined') {
           type = 1;            
           dynEl = $('<div id="notifyDivErr" class="notifyDiv" style="background:#dd0000;position:absolute;display:none;color:white;">' + errorMsg + '</div>');
                    dynEl.bind("click", function () {
                        $(this).remove();
                    });
       }
       else if (typeof saveMsg !== 'undefined') {
           type = 2;
           dynEl = $('<div id="notifyDivSucc" class="notifyDiv" style="background:#98bf21;position:absolute;display:none;color:white;">' + saveMsg + '</div>');
       }
       else if (typeof waitMsg !== 'undefined') {
           type = 3;
           dynEl = $('<div id="notifyDivWait" class="notifyDiv" style="position:absolute;display:none;"><img src="/desktopmodules/elura/images/ajax-loader.gif" />' + waitMsg + ' </div>');
       }
       if (type != 0) {
           targetEl.after(dynEl);
           var targetPos = targetEl.position();
           dynEl.css({
               'top': targetPos.top + targetEl.height(),
               'left': targetPos.left + targetEl.width() + 5
           }).fadeIn('slow');
           if (type == 2) {
               dynEl.fadeOut('slow', function(){
                   $(this).remove();
               });
           }
       }
   }

server side:

If Request.Headers("X-OFFICIAL-REQUEST-MINE") = "TRUE" Then
                AjaxWrapper()
            End If

Protected Sub AjaxWrapper()
        Response.Clear()
        Dim strData As String = ""
        Try
            Dim mi As MethodInfo = [GetType]().GetMethod(Request.Params("FUNCTION"), BindingFlags.Instance Or BindingFlags.NonPublic)
            Dim objs As Object() = New Object(mi.GetParameters().Length - 1) {}
            For i As Integer = 0 To objs.Length - 1
                objs(i) = (New PortalSecurity()).InputFilter(Request.Params("param" + CStr(i)), PortalSecurity.FilterFlag.NoMarkup)
            Next
            strData = mi.Invoke(Me, objs).ToString()
        Catch ex As Exception
            strData = "{Error : Caught}"
            Exceptions.ProcessModuleLoadException(Me, ex)
        End Try
        Response.Write(strData)
        Response.Flush()
        Try
            Response.Close()
        Catch
        End Try
        'It likes to break sometimes - and other times it's needed
        Response.[End]()
        Return
    End Sub

Protected Function saveOneCheckedCheckboxAjax(anQIdStr As String, checkedStr As String) As String
        saveOneCheckedCheckbox(Convert.ToInt32(anQIdStr), "checkedLevel2", Convert.ToBoolean(checkedStr))        
        Response.ContentType = "text"
        Return "1"
    End Function
