Autocomplete cannot work in The Dialog

[zhenzhu873]

try it yourself at jsbin: ​http://jsbin.com/ibimom/142/edit

on the jsbin url above,you can see that when you type a letter in an autocomplete box within a dialog, the result list was covered by the Dialog.

You need to instantiate the dialog first, or use autocomplete's appendTo option.
