About CJuiDialog for create new model

Using the Wiki "CJuiDialog create new model" (http://www.yiiframework.com/wiki/145/cjuidialog-for-create-new-model/) by Zaccaria, I have a problem when I try to make a link from dialog, the new dialogue that should show, not shown as a dialog, but within the context of previous dialog.

Any help is welcome.
