Please let me if anything wrong in code.I tried in page _Load and page_init events.Here is my code i am using it .........

{             

    Table tblControls = new Table();

    TableRow trControl1 = new TableRow();

    TableCell tdControl1 = new TableCell();

    tdControl1.Text = "<input id='Submit" + "' runat='server' type='button' value='Submit' onclick='alert('Yahooooo');' onserverclick='Submit_Click'></input>";

    trControl1.Cells.Add(tdControl1);                   

    tblControls.Rows.Add(trControl1);





    int i = 1;

    string strMessage = "hi";

    HtmlButton htmSubmit = new HtmlButton(); 

    htmSubmit.ID = "Submit" + i; 

    htmSubmit.InnerHtml = "Submit";



    htmSubmit.Attributes.Add("onclick", "alert('Yahoooooo');");





    htmSubmit.Attributes.Add("GuestId", "GuestUserId" + i.ToString()); 

    htmSubmit.Attributes.Add("UserId", "UserId" + i.ToString()); 

    htmSubmit.Attributes.Add("Message", strMessage); 

    htmSubmit.ServerClick += new System.EventHandler(this.Submit_Click);

}





protected void Submit_Click(object sender, EventArgs e)

{

    HtmlButton btn = (HtmlButton)sender; 

    string strGuestUserId = btn.Attributes["GuestId"]; 

    string strUserId = btn.Attributes["UserId"]; 

    string strMessage = btn.Attributes["Message"]; 

    Response.Write("Your have clicked " + btn.ID.ToString() + "<br/>" + strGuestUserId + "<br/>" + strUserId + "<br/>" + strMessage);

}

It looks like you're missing the statement where you add tblControls to the Page.Controls collection. You probably also intend for the dynamic button to be added to the tdControl1 control.
