Detect linkbutton id or text onclick created at runtime (Same function is being called on click of many linkbuttons)

 I have created some linkbuttons at runtime and add same function onclick of these functions. i.e. There are many link buttons and I have to call same function on click of any of these linkbuttons. I am unable to detect the link that calls that function inside the called function.
 My code:
   

              {
                LinkButton lnktest = new LinkButton();
                lnktest.ID = "kk" + i.ToString();
                lnktest.Text = "test";             
                lbl ...
