EO.web.dll v5.0.11.2 Asp.net 2

I'm having trouble using a custom column ClientSideGetText. I have a grid that works until I add the custom column and try to use the client function. I am using your example javascript function which should return "Excellent" defined in the page head.

Here is the column definition:
<eo:CustomColumn ClientSideGetText="on_column_gettext" DataField="cpasswd" HeaderText="Set Password">
</eo:CustomColumn>

Here is the sql for the OleDbDataReader that I am using:
Grid1.DataSource = this.user.GetReader("SELECT UserId, UserName, FirstName, LastName, '5' as cpasswd FROM USERS");

It works if I use all StaticColumn.

Here is the stack trace:
