Treeview does not reload correctly replaced items

[MrEugene]

Hi all,
I want to know if someone already have the same troubleshoot than me.

I have a treeview which show my C++ custom class objects.
I can add, select and delete all items in this treeview.

My troubleshoot is when I deleted any item an add another with the same "modelIndex", the treeview does not reload correctly the new item. When I tried to debug the "delegateItem" of treeview through "Component.onCompleted", I realize to treeview does not has access to the new item but I can edit it.

Do someone has any idea to resolve this ?

Finally, I have isolated the code which cause this behavior. But I do not know how fix it. Can you help me to understand the problem , please?

 Text{
                id: componentNameLabel
                anchors.horizontalCenter: parent.horizontalCenter
                anchors.verticalCenter: parent.verticalCenter

                Component.onCompleted:
                {
                    if(component.name === '')
                        componentNameLabel.text = component.type
                    else
                        componentNameLabel.text = component.name
                }
            }
