Can anyone help me whats is wrong with my setting or code.

I put the ChildBrowser.js in www folder

index.html

<script type="text/javascript" charset="utf-8" src="ChildBrowser.js"></script>

            function onDeviceReady()
            {
                var cb = ChildBrowser.install();
                if(cb != null)
                {
                    cb.onLocationChange = function(loc){ root.locChanged(loc); };
                    cb.onClose = function(){root.onCloseBrowser()};
                    cb.onOpenExternal = function(){root.onOpenExternal();};
                    window.plugins.childBrowser.showWebPage("http://google.com");
                }
            }

            function onLocationChange(loc) {
                navigator.notification.alert('Change to URL : '+loc);
            }
            function onClose() {
                navigator.notification.alert('onClose :');
            }
            function onOpenExternal() {
                navigator.notification.alert('onOpenExternal :');
            }

Issue was solved
Objective C files was not included properly.
I delete the reference of files and re include it.. then works fine...
