jquery function not being called

I'm trying to call a jquery function from a asp link button. Here is my link button html:

        <div style="padding-left:75px">
             <asp:LinkButton ID="lbAddCC" runat="server" ClientIDMode="Static" OnClick="ShowCCControls()" Text="Add CC"></asp:LinkButton>
         </div>
 

Here is my jquery function:

        function ShowCCControls() {
 
           $('#lblCC').show();
           $('#txtCC').show();
       } //end ShowCCControls()
 

When I try to build, I get the error:

ASP.internal_email_aspx does not contain a definition for 'ShowCCControls' and no extension method 'ShowCCControls' accepting a first argument of type 'ASP.internal_email_aspx' could be found (are you missing a using directive or an assembly reference?)

I have this working on another page using a check box:

                   <asp:CheckBox ID="chkNew" TabIndex="8" runat="server" Text="New Tank" OnClick="SetNewTankControls()"
                    ClientIDMode="Static" />
 

Anybody see an issue? Thanks
