Having put the SQL Method in quotes, it becomes an expression.
Putting an identifier in a call tag without quotes (like <!--#call 
MySQLMeth-->) calls that method, however, putting it in quotes, without 
adding parentheses, results in the statement returning the Python object, 
instead of calling the method. As you are using a call tag, you don't see 
what went wrong.

Change your code to:
	<!--#call "Data.InsertNew()"-->

And it will work.
