您如何通过Firebreath在XUL内调用javascript？

Question

I have written some javascript for my firefox extension in the XUL. This overlay has some cleanup functionality and I would like to be able to call the function through my NPAPI dll created via Firebreath.

I know that Firebreath has an example calling the "alert" function by doing the following:

// Retrieve a reference to the DOM Window
    FB::DOM::WindowPtr window = m_host->getDOMWindow();

    // Check if the DOM Window has an alert peroperty
    if (window && window->getJSObject()->HasProperty("window")) {
        // Create a reference to alert
        FB::JSObjectPtr obj = window->getProperty<FB::JSObjectPtr>("window");

        // Invoke alert with some text
        obj->Invoke("alert", FB::variant_list_of("This is a test alert invoked from an NPAPI Plugin"));
    }

The above code works so I've modified the Invoke to call my javascript function.

obj->Invoke("cleanupCode", FB::variant_list_of("0"));

This does not work and is confusing me on how I should be calling my javascript function.

How does your DOM look out ? Does window contain function named cleanupCode ? Maybe you can check it with firebug.
