I am facing an issue in with a parameter query grid. When I click on the current item and items display data. I put loader on an AJAX call but the loader is not working properly. It binds data not from the current item - it displays data from the previous item selected.

function tree_grid(ID) {
  $("#divLoading").show();

  $.ajax({
    type: "POST",
    url: '/Schedule/GetAllPresentation',
    data: "{ scheduleID: '" + ID + "',YearId:" + YearId + ",CompanyId:" + CompanyId + "}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    async: false,
    success: function(response) {
      $("#divLoading").hide();
      var data1 = [];
      data1 = $.parseJSON(response);
      data = data1;
    },
    error: function() {
      swal("", "Error in Data !", "error");
    }
  });
}
