How to make auto scroll up in iphone devices using SAP ui5??

I'm trying to scroll my list up by clicking on sync button that i have given, it's working fine in android devices but not in Iphone devices.

Here is my code:

var oSyncButton = new sap.m.Button('OrderSync');

oSyncButton.attachPress(null, oController.onSyncTap,null);

onSyncTap : function(event){

                            if(!isTimeOut){

                                 var filterValue = sap.ui.getCore().byId('dayTab').getSelectedKey();

                                 sap.ui.controller("OrderStatus").onLoadData(this,filterValue.toString());

                            }

                    },
