OnTextChanged doesn't work with AutoComplete

[Hans]

Hello,

I have the following textbox:
<asp:textbox id="txt_equipo" runat="server" AutoPostBack="true"
OnTextChanged="nombre_equipo" />

So when I write the code on the textbox it will automatically fill the
other fields like "name", "serial #", etc. It works, but when I use
the AutoComplete feature (when i enter a code for 2nd time) it
doesn't.

Any ideas ?

greetings,

hans
