How to call 2 events inside the datagrid

I have fetched a query in to the datagrids. Now I have added a new column to
the existing table (to the datagrid.)
In the new column I have placed 2 buttons. So when I click the first button
it performs some set of instruction. I actually made use of this procedure
DataGrid1_ItemCommand.

Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs)
End Sub

Now my question is how will able to use the other one? coz when I double
click the second button, it is nowhere land me in to a new procedure..

Let me know you thoughts..
