Communicate between DHTML and client application code - VS 2008

Question

I followed this article: How to: Implement Two-Way Communication Between DHTML Code and Client Application Code

Based on this example, I can establish the communication between DHTML and Client code. Now if I introduce a master page, none of the communications work. Are there different rules when Master Pages are used?

I also looked at this: How to add startup JavaScript code from Content Page to Master Page

The reason I am experimenting is that I have a gridview control and when user clicks on each row in the grid view control, in the OnrowCommand of grid view control, i want to raise the event to communicate with the client application code
