Resources updated only after Clean All

So, I have a file 'html.qrc':

<RCC>
<qresource prefix="/">
<file>jquery.js</file>
<file>index.html</file>
</qresource>
</RCC>

It's added into my Qt project. In main.cpp code I create QWebView and set its html contents with contents of index.html

Problem is, when I update index.html, changes are not visible in the application, only after Clean All in Qt Creator.
