Error on save with Qt 5.9

I'm using for display data in a list that code:

Model declaration

var dbConn = new QuickModel.QMDatabase('MyProject', '1.0');

var Documento = dbConn.define('Documento', {
  conteudo: dbConn.String('Conteudo', {accept_null:false}),
  dtHrInclusao: dbConn.DateTime('Data/Hora de Inclusão', {accept_null:false, 'default': 'CURRENT_TIMESTAMP'}),
  dtHrExclusao: dbConn.DateTime('Data/Hora de Exclusão')
});

Adding a documents (works fine)

var l_doc = Model.Documento.create({conteudo: a_data});
documentsModel.append(l_doc);

Error here when I try to update:

var l_doc = documentsModel.get(a_itemIndex)
l_doc.dtHrExclusao = new Date();
l_doc.save(false);

Error is Property 'save' of object QObject(0x7fdb0ed50c90) is not a function

var l_doc = Model.Documento._makeObject(documentsModel.get(a_itemIndex))
l_doc.dtHrExclusao = new Date();
l_doc.save(false);

But same error;

Only works with:

var l_doc = documentsModel.get(a_itemIndex)
Model.Documento.filter({id: l_doc.id}).update({dtHrExclusao: new Date()});
