How can I read listmodel role property in main.qml?

Question

In main.qml, I am updating listModel dynamically on every function addItem() call. Herein, I am setting two role; buttonTypeRole and source. OneText.qml file has a Text field. Actually, after inserting buttonTypeRole and source into listModel, I want to know whether source is being truncated or not.

IS ANY WAY TO READ OneText.qml TEXT TRUNCATED PROPERTY IN main.qml FILE?

main.qml

function additem()
{

 listModel.insert(tlist.listModel.count , {"buttonTypeRole":"OneText.qml", "source":editText})
 console.log("model-- "+tlist.listModel.get(sourceIndex).t)
}
