How to trigger action chains from a button defined in editable row template in vbcs?

Content

Hi ,

I am working on editable table, where in one of the column user should be able to open a dialog by clicking on the icon/button. I am able to display an icon and have defined on-click event on the icon but it is not working. I am attaching the code and screen shot. 

Appreciate your inputs to resolve this issue.
