Inserting QWebEngineScript on next page run time.

[Zee_07]

I want that whenever a button on web-page (let's say a.html) get clicked my slot in core class i.e. (QWebChannel->registerObject("core", core);) gets called and it working very well only when I start calling WebEngineView->load(a.html).
But if I am redirecting from B.html to A.html then slot not gets called. Fallowing is my code snippet:

QWebEngineView *webEngine = new QWebEngineView(this);

QWebEngineProfile *profile = new QWebEngineProfile("MyWebChannelProfile", webEngine);

QWebEngineScript script2;
    script2.setSourceCode(createJsStringAfterLoad()); //here in this function I am creating my java script code which will call core class slot
    script2.setName("qwebchannel2.js");
    script2.setWorldId(QWebEngineScript::MainWorld);
    script2.setInjectionPoint(QWebEngineScript::DocumentReady);
    script2.setRunsOnSubFrames(true);
    profile->scripts()->insert(script2);

QWebEnginePage *myPage = new QWebEnginePage(profile, m_webEngine);
    webEngine->setPage(myPage);

    QWebChannel *channel = new QWebChannel(myPage);
    webEngine->page()->setWebChannel(channel);

    Core *core = new Core(this);   //in this class my slot is present which I want to get called
    channel->registerObject("core", core);
 m_webEngine->load(a.html);

Please let me know how to insert the QWebEngineScript on next redirected page without knowing its url.
