'list' object is not callable

BreakBad

Moving from PyQt to PySide, I'm noticing one of my views are spamming the error "TypeError: 'list' object is not callable". It seems the headers display normally, however the data method is not being executed and data is not displaying. Any insight appreciated.

Qt 4.7.3
PySide 1.1.0
Python 2.7.3

@from PySide import QtCore,QtGui

class ScenarioOutputModel(QtCore.QAbstractItemModel):
def init(self):
super(ScenarioOutputModel,self).init()
self.headers = []
self.data = []

def add_rows(self,rows):
    self.beginInsertRows(QtCore.QModelIndex(),self.rowCount(),(self.rowCount()+len(rows)-1))
    self.data.extend(rows)
    self.endInsertRows()
    
def clear(self):
    self.data = []
    self.reset()

def index(self,row,column,parent):
    """ Return index given a row, column, and parent index.
    param int row
    param int column
    param QModelIndex parent
    return int
    """
    return self.createIndex(row, column, QtCore.QModelIndex())

def getNode(self,index):
    """ Return node of corresponding index.
    param QModelIndex index
    return Node
    """
    if index.isValid():
        node = index.internalPointer()
        if node is not None:
            return node
    return self.data

def parent(self,index):
    """ Return parent index of given index.
    param QModelIndex index
    return QModelIndex
    """
    return QtCore.QModelIndex()

def flags(self,index):
    return QtCore.Qt.ItemIsEnabled|QtCore.Qt.ItemIsSelectable

def set_headers(self,headers):
    self.headers = headers
    self.headerDataChanged.emit(QtCore.Qt.Horizontal,0,len(headers)-1)

def headerData(self,section,orientation,role=QtCore.Qt.DisplayRole):
    
    if orientation == QtCore.Qt.Horizontal and role == QtCore.Qt.DisplayRole:
        return self.headers[section]
    
    return None

def rowCount(self,index=QtCore.QModelIndex()):
    return len(self.data)

def columnCount(self,index=QtCore.QModelIndex()):
    return len(self.headers)

def data(self,index,role=QtCore.Qt.DisplayRole):
    if not index.isValid():
        return None
    if role == QtCore.Qt.DisplayRole:
        print 'data'
        return self.data[index.row()][index.column()]
    return None

if name == 'main':
import sys
app = QtGui.QApplication(sys.argv)

table_view = QtGui.QTableView()
model = ScenarioOutputModel()
table_view.setModel(model)

model.set_headers(['H%s'%s for s in range(10)])
model.add_rows([[str(y) for y in range(10)] for x in range(10)])

mw = QtGui.QMainWindow()
mw.setCentralWidget(table_view)
mw.show()

sys.exit(app.exec_())

Apparently naming a local variable the same as an method was tolerated somehow in pyqt. Renaming self.data to something else relieved the issue.
