Enabling associated buttons after executing setSelectionRow method of JTreeTable object

I am using setSelectionRow method and it is successful in selecting desired row . I have verified it by using getSelectedRow. some buttons are suppose to enable after selecting the row ,but some these buttons are not getting enabled when the selection happens whereas it happens when I do manually. 

There is no change occurred in our product. I need TestComplete to enable these buttons how it was earlier.
