Setting cusros position does not work in text_changed callback

[Deekshit Mantampady]

Hi all,
   I am not able to set the cursor positon in an entry widget using
gtk_editable_set_position(), inside a textchanged callback. In the
following code, I always set the cursor postion to 0, for each text
changed. But it does not happen.

Please help me.

Thanks in advance
