Perhaps use the currentIndex() method on the combobox inside your
changeValue function ...
def changeValue(self, value):
mc = self.canvas
layer = mc.currentLayer()
obj= layer.selectedFeatureIds()
layer.changeAttributeValue(
int(obj[0], *yourComboBox.currentIndex()*, value)
You can also use a not very highly recommend way, with lambda, however it
sucks for garbage cleanup, it's sloppy python,and you will no longer get
your QString passed.... off the top of my head it would be something like
....
QObject.connect(comboBoxNew[dropbox_counter],SIGNAL("currentIndexChanged(QString)"),
lambda: self.changeValue(self, dropbox_counter))
