I solve the problem.
CAUSE: When deploying the projectI was placing the folders "admin", "Grappelli" and "templates" in the project root, and setting the variable STATIC_URL on the source "settings.py" with the value '/'.
Then some javascripts could not be accessed.
SOLUTION: To solve the problem, I set the variable STATIC_URL with the value '/static/' and put the three folders within a folder called static in the production version. Hence, all functions started to operate. :D
P.S.: I also edited httpd.conf with these config:
Alias /static "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs/OdontoWeb/static"
<Directory "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs/OdontoWeb/static">
Order allow,deny
Allow from all
</Directory>
<Location "/static">
SetHandler None
</Location>
