QDeclarativeListProperty add item from qml application

is there any why to add item to QDeclarativeListProperty from qml file at run time?
in a loop, for example.

Code:

---

var i;
                    for(i = 0 ; i < listOfItems.length ; ++i)
                    {
                        listOfItems.append(MyItem {
                                                     text:"list"+i
                                                 })
                    }

---

and listOfItems is the QDeclarativeListProperty list...
i dont want to do it like this:

Code:

---

listOfItems:
            [
                MyItem   
                {
                    text:"list val1"
                },
                MyItem                                                 
                {
                    text:"list val2"
                }
                ......

Have you by chance found an answer to this? I'm having the same problem and I couldn't find an answer anywhere.
Thanks.
