QWebView values are updated but correspondingly its not updating on click.

appollosputnik

[code]
QWebElement selectBox2 =
m_WebView->page()->mainFrame()->findFirstElement("select[id=hostid]");
selectBox2.setFocus();
selectBox2.evaluateJavaScript("this.selectedIndex = 2");

QWebElement button_click = m_WebView->page()->mainFrame()->findFirstElement("input[type=submit]");
if(button_click.isNull())
    return;
button_click.evaluateJavaScript("this.click()");

[/code]
Please check the snippet above. I am able to make a selection from the option and able to click. But it seems the selection is not updated in QWebView. So when it's click it doesnt show me the updates. I think although I can see in QWebView the values are changed but it's not updated with the changed values.
Please help me whats going wrong in this... Thanks Sujan
