[jQuery] [autocomplete] - unautocomplete destructor

[Imposter]

Hi -

unautocomplete() doesn't seem to be working for me.  autocomplete
works fine with:

$("#<%=txtCustName.ClientID %>").autocomplete("auto_complete.aspx",
                {  da da da .......

A button click on the form indeed executes the following statement.
(The .NET ClientID part I'm sure is correct):

$("#<%=txtCustName.ClientID %>").unautocomplete();

Am I doing something wrong?

Thanks for any help ...
