Unable to bind the function with widget

[ANKUR AGGARWAL]

Hey

I am a newbie to ubuntu app  development. Was learning the tutorial of
creating the first ubuntu app (John bacon's video) and got stuck somewhere
in the middle. I am unable to bind a function to the button. I am getting
warning message as

bin/firstapplication:72: RuntimeWarning: missing handler
'on_refreshButton_clicked'
  self.builder.connect_signals(self)


I want to bind my refresh button named as 'refreshButton' with this
function

def on_refreshButton_clicked(self,widget):
         print "refresh"


when I run the code using quickly and press on the button I am getting the
upper warning message. Searched the web for the same but I am unable to
find a solution. Please help me out in this.


Thanks & Regards
Ankur Aggarwal
