      It is not possible to have a JS function inside the model of eg. a Repeater and then trigger it. Neither from the delegate using modelData.trigger() nor by accessing it by index.

      Repeater {
    model: [
        {
            label: "Trigger",
            trigger: function() {
                console.log("Hello")
            }
        }
    ]

    Button {
        text: modelData.label
        onClicked: modelData.trigger()
    }
}

      Clicking the button will just yield an error rather than invoking the function.

      TypeError: Property 'trigger' of object [object Object] is not a function
