Get latest data in mobile app

Can you please let us know a way to get latest data for record in a mobile app view. We added custom action like this 

Ext.define("Terrasoft.MyAction", {

    extend: "Terrasoft.ActionBase",

    config: {

        useMask: false,

        title: "MyActionTitle",

        iconCls: Terrasoft.ActionIcons.Copy

    },

    execute: function(record) {

       this.callParent(arguments);

                                var UsrURLDocuSign = record.get("UsrURLDocuSign");

                                window.open(UsrURLDocuSign, '_system')

                                var modelName = "Order";

       // alert(UsrURLDocuSign + "---1kjbdsk ks1111--" );

       this.executionEnd(true);

    }

});

But the problem is some time that url or data is not latest data, is there a way to load the latest data using something? I already tried getEntity but it does not seem to work.
