unable to deploy Django on ubuntu with apache mod WSGI

I am using ubuntu 12.04 and I did the following:

sudo apt-get install python-mysql

sudo python setup.py install (install Django 1.6.2)

sudo apt-get install mysql-server-...

sudo apt-get install apache2

sudo apt-get install libapache2-mod-wsgi

Here are my configuration files:

/home/firstweb.wsgi:

import os
import sys
sys.path = ['/var/www/firstweb'] + sys.path
os.environ['DJANGO_SETTINGS_MODULE'] = 'firstweb.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

/etc/apache/sites-availables/firstweb.conf:

<VirtualHost *:80>
WSGIScriptAlias / /home/adel/firstweb.wsgi
ServerName firstweb.com
Alias /static /var/www/firstweb/static/

<Directory /var/www/firstweb/>
order allow,deny
Allow from all
</Directory>
</VirtualHost>

then I did:

1. a2ensite firstweb.conf
2. cd /var/www/
3. django-admin.py startproject firstweb
4. apachectl restart
5. vi /etc/hosts

and add the following (192.168.0.123 is my wlan ip)

192.168.0.123 firstweb.com

I use mysql and I create a database and change the settings.py and the syncdb works fine

But when I enter the www.firstweb.com in browser the default page of Apache appears (it works....)

and the Django default page does not appear!!

what is wrong with my configuration?

thank you.
