New plugin implementing new task not works in batch

Hi all!
I have a plugin wich implementing new task
So plugin code look like:

 public void InstallScheduleTask()
        {
            ScheduleTask data = new ScheduleTask { Enabled = true,
                                                   Name = _localizationService.GetResource("Plugins.Integration.PaymentImport.Taskname"),
                                                   Seconds = 3600,
                                                   StopOnError = false,
                                                   Type = "Nop.Plugin.Integration.PaymentImport.PaymentImportTask, Nop.Plugin.Integration.PaymentImport"
            };

            _scheduleTaskService.Insert(data);
        }

  public override void Install()
        {
            var corePlugin = _pluginFinder.GetPluginDescriptorBySystemName("Integration.ODBC");

            if (corePlugin != null && corePlugin.Installed)
            { 
                //locales
                this.AddOrUpdatePluginLocaleResource("Plugins.Integration.PaymentImport.Taskname", "Импорт статусов заказов");
                this.AddOrUpdatePluginLocaleResource("Plugins.Integration.PaymentImport.Taskname.Hint", "Загрузка статусов оплат по заказам из ERP.");

                InstallScheduleTask();

                base.Install();
            }
        }

And class with task looks like

class PaymentImportTask : ITask
{
    public void execute()
{
}
}

So it works on my local machine fine even in a batch. But on production, after I install its plugins nothing happens. Its work only if u push button but not in a batch.
