$.ajax not working on Scheduler Client Event - IPad

[Surabhi]

Hi

I have a Scheduler Control where i have defined a function on onclientappointmentmoveend="OnClientAppointmentMoveEnd" and within my function i have something like this

function OnClientAppointmentMoveEnd(sender, eventArgs) {
    MyFunction(eventArgs, "onMove");                
 }

function MyFunction(eventArgs, action) {
    $.ajax(
     {
          url: url,
          data: parameter,
          contentType: "application/json; charset=utf-8",
          success: 
          function (data) {
               CallbackFunction(data, eventArgs,action);
           },
      type:'POST',
      dataType: 'json',
      async: false
 });

}

function CallbackFunction(data, eventArgs,action) {
..........
.......
.........

}

Now, my callback function works fine on any windows browser but this callback function is not executed on IPad. Is there something that is missing to make it execute on IPad?
