AjaxAutoComplete not working after migration to C#

Question

My autocomplete works fine when using my old site but does not work when I ported over to C# and Entity Framework. The below HTML is part of a user control. I've put breakpoints in the webservice code and it doesn't even look like it's getting called. I don't know where else to check to see where the break is. Any help would be appreciated. Thanks.

                         <asp:TextBox ID="TextBoxDamName" runat="server" Columns="50"></asp:TextBox>
                    <asp:AutoCompleteExtender ID="TextBoxDamName_AutoCompleteExtender"
                        runat="server"

Turns out that I wasn't directing the control to the correct locatioin for my Webservice file. Once I fixed that I still wasn't getting results even though I was hitting the method in the webservice. Turns out I wasn't return the results correctly. I fixed it by turning this

            return EE.DamSafetyDatas
                .Take(count)
                .Where(c => c.DamName.StartsWith(prefixText))
                .Distinct()
                .OrderBy(c => c.DamName)
                .Select(c => c.DamName)
                .ToArray();

to

            return EE.DamSafetyDatas
                 .Where(c => c.DamName.StartsWith(prefixText))
                .Distinct().Take(count)
                .OrderBy(c => c.DamName)
                .Select(c => c.DamName)
                .ToList.ToArray();

I also had to change the location of the .Take(count) because it would take the first (count = 10) from the list THEN filter them by starts with.
