GridView Filter with pjax within <form> tag

[strtob]

Your great plugin is essential for my projects, thanks a lot again!

I've a tabbed update form, one tab is fitted out with the kartik gridview and sources by a dataProvider as well as searchProvider.

Everything works fine so far, but if try to use the filter, the entire page we load. It seems that the input field of the filter fire the form action. How can I manipulate the code that the filter works?
