ListElement cannot use script for property value in ListElement (QML)

Hello,
I am trying to update the values of roles in ListElement.
Here is my Example.qml file

Code:

---

Item{
 
    property string title :""
    property string tags: ""
    property string name: ""
 
}

---

Here is myModel.qml

Code:

---

ListModel{
 
    ListElement{source: myExample.tags  }
 
}

---

and here is the main.qml

Code:

---

Rectangle {
    width: 600
    height: 600
    Text {
        x: 66
        y: 93
        text: "Hello World"
    }
 
 
    Example{id:myExample}
 
}

---

What I am not allowed to do above is to use "myExample.tags" as the value of role of a ListElement. The error is the following:

Quote:

---

ListElement: cannot use script for property value
ListElement{source: myExample.tags }

---

Is there any other way to update the roles inside the ListModel?
Is it possible to create a ListModel in C++ and use it in QML as plugin?
