addCallback is a method of twisted.internet.defer.Deferred,
but I don't think your node is a Deferred.

This looks as though it will return a Deferred, from the callRemote.
If that isn't the case, ignore everything else below.
So you might write:
def get_platform(self):
""" Returns node type
"""
self.model = self.get_model()
self.model.addCallback(self.success)
return self.model
def success(self, model):
print '1111fff'
return model
And then you could use the value returned by get_platform (which is a
Deferred)
by adding a callback to it:
def loadConfig(self, id, config = None):
""" Load the config
"""
node.get_platform().addCallback(self.textLabel_Platform.setText)
When the callRemote succeeds, it calls the callbacks on the Deferred.
First, it passes the return value from the remote call to success().
Then
it passes the return value from success() to textLabel_Platform.setText.
