why onserverclick does not work in href in asp.net - asp.net

Question

I have problem that onserverclick attribute does not work ,the method which assigned to it does not trigger.
string strTr = "";
for (int i = 0; i < adminuserlist.Count; i++)
{
strTr += string.Format("<tr id=\"tr\">" +
" <td>{0}</td> " +
" <td>{1}</td> " +
" <td>{2}</td> " +
" <td>{3}</td> " +
" <td>{4}</td> " +
" <td>{5}</td> " +
" <td>{6}</td> " +
"<td class=\"col-lg-2\">" +
" <a href=\"#\" id=" + i +
"runat=\"server\" onServerClick=\"MyFuncion_Click\"
class=\"table-icontoolbar\" data-toggle=\"tooltip\" data-
placement=\"top\" title=\"Edit\"> " +
" <img
src=\"../images/icon-edit.png\"></a> " +
" <a href=\"#\"
runat=\"server\" onClick=\"bll();\"
onServerClick=\"MyFuncion_Click2\" class=\"table-icontoolbar\"
data-toggle=\"tooltip\" data-placement=\"top\"
title=\"Delete\">" +
" <img
src=\"../images/icon-delete.png\"></a>" +
" </td> " +
" </tr>",
adminuserlist[i].AdminUserName,
adminuserlist[i].AdminUserPassword,
adminuserlist[i].AdminUserEmail,
adminuserlist[i].AdminUserType, adminuserlist[i].IsActive,
adminuserlist[i].isDeleted,
adminuserlist[i].CreatedOn);
tbodyAdminUserView.InnerHtml = strTr;
}
and this the function which should be triggered:
public void MyFuncion_Click(Object sender, EventArgs e)
{
Label1.Text = "vvvv";
}
