Hi Everyone, Can anyone help to set BusyIndicator in button controller

if (!this.busyFragmentForm) {

this.busyFragmentForm = new sap.ui.xmlfragment(this.createId("bsyDlgForm"), "cus.sd.salesorder.create_store.view.BusyDialog", this); this.getView().addDependent(this.busyFragmentForm); }

this.busyFragmentForm.open();

I tried this one and some other functions like showBusyIndicator.open(), set Busy(true). But those are not working in the controller

onNavigateSubmit: function(oEvent) {

// here i have other function call;

}
