        OntarioMaps {

        }

The exact error I get is : 
qrc:/qml/OntarioMapsForm.qml:112: TypeError: Property 'geoCode' of object QQmlDMAbstractItemModelData(0x1b06e4c0e00) is not a function

I tried my best to only include important parts so "..." is where other code would go. I have geoCode() as invokable so I'm not sure where the issue lies. Thanks for your help! Also the geoCode() call is at the end of QML and model.setSuggestions(text) works.

@CaptainJuice you have instantiated your OntarioMaps with the name model. Try renaming it & obviously update anywhere you reference it. I think when you try to access it in your delegate it is being hidden by the model property of the delegate.

@Bob64 Thankyou! It works now!
