Opening New Form does not work.

[bmps]

I have built a GUI and its working. I need to put in a page where ill put in some details of the GUI and the Licenses and End User rights for the GUI. For this i have a Push Button which when clicked should open another form where i have a Text Browser and a Link which directs to the GPL 3.0 Licenses etc. But for some reason the second form is not being called when i click on it. This is the code that i have written. Please let me know where am going wrong.
My first form where my basic GUI is created is test.ui(which has its own test.h and test.cpp). And now i have added a dialog.ui(which has a dialog.cpp and dialog.h). My pushbutton is in test.ui whiuch when called should start the dialog.ui.

void unametest::on_pushbutton_clicked()
{
    dialog *dlg=new dialog(this);
    dlg->show();
    dlg->raise();
    dialog->activateWindow();
}

void unametest::on_pushbutton_clicked()
{
    dialog *dlg=new dialog(this);
    dlg->show();
    dlg->raise();
    dialog->activateWindow();
}
