Render enum as string in ClientTemplate in Grid

The following grid column definition renders the enum as a string:

columns.Bound(p => p.SomeEnum);

The ajax call actually returns an int for the enum but the grid does some magic and shows the enum string.

If I need to customize the output and use a ClientTemplate, it renders as an int though:

columns.Bound(p => p.SomeEnum).ClientTemplate("foo #=SomeEnum#");

How can I get my ClientTemplate to render the string version of the enum?
