Can the "Ask a question" form be override ?

[TBoele]

I make a copy of  .../components/com_virtuemart/views/askquestion/tmpl/form.php  and placed it in  .../templates/my_template/html/com_virtuemart/askquestion/form.php 
But when i made some changes it doesn't work. You see the changes if i do it in the original form.php.

Is it not possible to override this ask a question form.php ?
