[PyQt] QsciScintilla Lexer disappears?

I am trying to use QsciScintilla in a project but I am having some trouble
with the Lexer. I don't understand why this code shows the lexer at
the end of __init__ but when clicking in the margin it shows None.

Any thoughts?

import sys
from PyQt4.QtCore import SIGNAL
from PyQt4.QtGui import QApplication
from PyQt4.Qsci import QsciScintilla, QsciLexerPython

class SimplePythonEditor(QsciScintilla):
    def __init__(self, parent=None):
        super(SimplePythonEditor, self).__init__(parent)

        self.setMarginSensitivity(1, True)
            SIGNAL('marginClicked(int, int, Qt::KeyboardModifiers)'),

        lexer = QsciLexerPython()
        print self.lexer()

    def on_margin_clicked(self, nmargin, nline, modifiers):
        print self.lexer()

if __name__ == "__main__":
    app = QApplication(sys.argv)
    editor = SimplePythonEditor()
