Binding Data bound event

[Tx3]

$('#ResourcesTreeViewPhrasesTab').bind('databound', function (event) {
   phrasesTreeOnDataBound(event, isChecked);
});
tv.expand($branch);

It seems when we are using server side data binding with on-demand. Data bound event isn't never triggered even if branch is expanded and loaded correctly. Any ideas?

We are using version 2010.3.1220
