QML objectModel

ODБOï

Hi,
i'm trying to create objects list (qml side) with values that i read in file with c++ methode.

when on_PropValsChanged is emited i have to create object with the properties inside _propVals variant, and i need to keep the objects somewhere i can access it whenever i need

So i tryed to put my objects in a ObjectModel as described here
http://doc.qt.io/qt-5/qml-qtqml-models-objectmodel.html
and show them in ListView

but as soon i click on my ListView (to scroll) my app crashes

calling objectMod.get(some index)._name will also result to a crash

The process was ended forcefully.

// object creation

 on_PropValsChanged: {
     
        var tmp = _propVals
        var comp = Qt.createComponent("Obj.qml")
        var obj = comp.createObject(cont)
 
        obj._vId=tmp[0]
        obj._name=tmp[1]
        obj._alias = tmp[2]
        obj._slaveId= tmp[3]
        obj._storageType =tmp[4]
        obj._dataType =tmp[5]
        obj._bitSz= tmp[6]
        obj._bitOffset =tmp[7]
        obj._slaveFixAdress = tmp[8]
        obj._type = tmp[9]
        obj._direction = tmp[10]
        obj._index = tmp[11]
        obj._motionType = tmp[12]
        obj._motionDirection = tmp[13]
        obj._motionIndex = tmp[14]

        objectMod.append(obj)
   
    }
  ObjectModel {
        id: objectMod
        onChildrenChanged: console.log(children) // the objects are added with the prop values correctly

    }

//Obj.qml

Rectangle {
    property string _vId : ""
    property string _name : ""
    property string _alias : ""
    property string _slaveId : ""
    property string _storageType : ""
    property string _dataType : ""
    property string _bitSz : ""
    property string _bitOffset : ""
    property string _slaveFixAdress : ""
    property string _type : ""
    property string _direction : ""
    property string _index : ""
    property string _motionType : ""
    property string _motionDirection : ""
    property string _motionIndex : ""


    ColumnLayout{
        anchors.fill: parent

        RowLayout{
            Text{
                text : "variable id :"
            }
            Text{
                text : _vId
            }
        }
}

If someone has a better approche please tell me how should i do.
