发送ajax表单重新加载页面而不是发送请求

I'm struggling to create a shoutbox for django. Everything works fine now concerning reading data from the database, but when I want to add a new shout the whole page is being reloaded, and from what I was able to check - form's action remains the same, and there is no request sent to function under specified url. What am I doing wrong here ?I'm struggling to create a shoutbox for django.
