using Attribute.Add("onclick"... to call a code behind function

Hi,

I have UltraWebGrid which I create dynamically, using DataBind and a helper class.
In the InitializeRow event, I generate ImageButtons in one of the columns.

Clearly, since it's ImageButton I need it to call a function.
normally, I set the function using Attribute.Add, and call a javascript:

img.Attributes.Add("onclick", "DoSomething();");

But Some of the functions should be server side (since it supposed to call the business logic layer).
I know that if I have a code-behind OnClick function and I would like to add client-side command I could do something like that:

this.btnSomething.Attributes.Add("onclick", "JavascriptFunction();" + this.Page.ClientScript.GetPostBackEventReference(btnSomething, "").ToString());

But it calls the code-behind function which is already attached to the buttons and just adds the Javascript function.

How can I call a code behind function which is not connected in any way to the imagebutton dynamically? (I currently use Attribute.Add, but if there's some other way to do that - I'd love to know)

Thanks.
