Grid Row Template - Different behavior between hard code columns and dynamic columns

[CesarAfonso]

Hi,

I found out there's a different behavior between hard code columns and dynamic columns, when you setup the template for the column.
In both scenarios the column is a select/option. But in the first case when I edit the row, both inline and popup editing will load the template, in the second case the edit mode will lose the select/option and will transform it in a input string field.

Here is the use case : https://gist.run/?id=76e5ca56f2763ac4fff1639d9ec5afdc

Am I missing something or it's a bug?
