How to handle OnRowClick event of ASPxGridView in code behind

I am using ASP.Net with VB to display records in a grid view.
In a normal ASP GridView, I can simply handle SelectedIndexChanged Event from code behind like this:

Sub mySub(ByVal sender as Object, ByVal e As EventArgs) 
          Handles GridView1.SelectedIndexChanged
  Dim id as String = GridView1.SelectedRow.Item(0).ToString
  Response.Redirect("Customer.aspx?ID=" & id) 'Or Whatever
End Sub

Now I am trying to do the same but with ASPxGridView that comes with DevExpress. Obviosly, there is no built in Event that can be handled directly from code behind. I have to go through client click with javascript, which I don't mind to but all my attempts to pass the click event from the client to the server code behind failed.

Here is my ASP page

<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False"
     KeyFieldName="id" Width="550px" OnSelectionChanged="row_selected" >
    <SettingsBehavior AllowFocusedRow="True" />
    <SettingsText Title="Customers" />
    <Columns>
        <dx:GridViewDataTextColumn FieldName="id" ReadOnly="True" VisibleIndex="1">
            <EditFormSettings Visible="False" />
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn FieldName="Name" VisibleIndex="2">
        </dx:GridViewDataTextColumn>
    </Columns>
    <Settings ShowTitlePanel="True" />
    <ClientSideEvents FocusedRowChanged="function(s, e) {
        row_selected();
        }" />
</dx:ASPxGridView>

And here is my code behind (Which never gets called)

Sub row_selected()
    Dim id as String = ASPxGridView1.SelectedRow.Item(0).ToString
    Response.Redirect("Customers.aspx?ID=" & id) 
End Sub

How can I call a function from code behind by clicking on a row on ASPxGridView row?
