Passing signal from QML to C++ with parameter

[psbhardwaj09gmail.com]

Hi,
I have an application where i want to pass signal from qml to c++.
code in qml as

signal blockUri(int uri)

mainView.blockUri(index)// calling signal

in c++ is as

QObject *rootObject = mpView->rootObject();
QObject::connect(rootObject, SIGNAL(blockUri(int)), this, SLOT(printData(int)));

void someclass::printData(int uri)
{
qDebug()<<"Text From QML:"<<uri;
}

but text is not printing in C++ code.
i know i am doing something wrong.
So please any one can help me.
