I am trying to make the item in my QTreeWidget editable and I am not successful

heres the code making my tree, please help me point out what should i do to make it editable

Qt Code: 
  1. for (int i = 0 ; i < keyList.count(); i++) // keylist is declared as QStringList
  2.         {
  3.             QTreeWidgetItem *headItem = new QTreeWidgetItem(treeSensor);
  4.             headItem->setText(0, QString("HD%1").arg(keyList.value(i)));
  5.             headItem->setCheckState(0, Qt::Unchecked);
  6.  
  7.             for (int j = 0 ; j < 2; j++)
  8.             {
  9.                 QTreeWidgetItem *axItem = new QTreeWidgetItem(headItem);
  10.                 axItem->setText(0, QString("A%1").arg(j+1));
  11.                 axItem->setCheckState(0, Qt::Unchecked);
  12.                 strColor = color(colorNames); // generates a color name known to Qt
  13.                 axItem->setData(1,Qt::DecorationRole,QColor(strColor));
  14.                 axItem->setData(1,Qt::DisplayRole,strColor);
  15.                 axItem->setFlags(axItem->flags()|Qt::ItemIsEditable); //this did not work
  16.  
  17.                 QTreeWidgetItem *radItem = new QTreeWidgetItem(headItem);
  18.                 radItem->setText(0, QString("R%1").arg(j+1));
  19.                 radItem->setCheckState(0, Qt::Unchecked);
  20.                 strColor = color(colorNames);
  21.                 radItem->setData(1,Qt::DecorationRole,QColor(strColor));
  22.                 radItem->setData(1,Qt::DisplayRole,strColor);
  23.  
  24.                 QTreeWidgetItem *cirItem = new QTreeWidgetItem(headItem);
  25.                 cirItem->setText(0, QString("C%1").arg(j+1));
  26.                 cirItem->setCheckState(0, Qt::Unchecked);
  27.                 strColor = color(colorNames);
  28.                 cirItem->setData(1,Qt::DecorationRole,QColor(strColor));
  29.                 cirItem->setData(1,Qt::DisplayRole,strColor);
  30.             }
  31.             QTreeWidgetItem *eddyItem = new QTreeWidgetItem(headItem);
  32.             eddyItem->setText(0, QString("ED"));
  33.             eddyItem->setCheckState(0, Qt::Unchecked);
  34.             strColor = color(colorNames);
  35.             eddyItem->setData(1,Qt::DecorationRole,QColor(strColor));
  36.             eddyItem->setData(1,Qt::DisplayRole,strColor);
