You can inject JavaScript using the method 
QWebElement::evaluateJavaScript()

Also you can insert a Python object in the JS runtime with 
QWebFrame::addToJavaScriptWindowObject()
see here:

pyqts.html


so make a Python object with some methods you'd wish to call, then 
evaluate some small JS that will bind the click event on your element to 
the method of the Python object.
