Just like you for setting the data in the model, you retrieved the data
model with dataModel = tree.getDataModel() and then set the data in the
model by calling dataModel.setData(), you also need to retrieve the data
from the model by calling the getData() method on the data model.
Instead of:
var data = tree.getDataModel();
you want:
var data = dataModel.getData();
