How to uncheck a checked radio buttons in pyqt4

Question

Im making a quiz and after my next button is pressed i want the the radio buttons to be unchecked but this isnt happening. Here is where i put the radio buttons.

self.answers = QtGui.QButtonGroup(self) 
self.Correctanswer = QRadioButton()
self.Incorrectans1 = QRadioButton()
self.Incorrectans2 = QRadioButton()
self.Incorrectans3 = QRadioButton()
self.answers.addButton(self.Correctanswer)
self.answers.addButton(self.Incorrectans1)
self.answers.addButton(self.Incorrectans2)
self.answers.addButton(self.Incorrectans3)
self.answers.buttonClicked.connect(self.QuestionCheck)
self.Correctanswer.setAutoExclusive(True)
self.Incorrectans1.setAutoExclusive(True)
self.Incorrectans2.setAutoExclusive(True)
self.Incorrectans3.setAutoExclusive(True)

Here the subroutine which is connected to my next button. And here i try to set the radio buttons to be clear but that isnt happening. The radio button still has its previous choice from the last question.

def Showquestions2(self):
    self.Questionum.setText("Question 2")
    self.Correctanswer.setChecked(False)
    self.Incorrectans1.setChecked(False)
    self.Incorrectans2.setChecked(False)
    self.Incorrectans3.setChecked(False)
    self.ismultichoiceButton.clicked.connect(self.Showquestions3)

Could anyone tell me where im going wrong? thanks
