ASP Buttons not working after changing ActiveViewIndex

I'm using MultiView to build a multi step form. The next button works on the first step (ViewOne) but then both the next and back buttons do nothing at the next step (ViewTwo).

I don't know if there is any clue in the below code or you need to see more?... 

 <asp:MultiView ID="MultiView2" runat="server" ActiveViewIndex="0">
 <asp:View ID="ViewOne" runat="server">
 </asp:View>
 <asp:View ID="ViewTwo" runat="server">
 </asp:View>
 </asp:MultiView>
 <asp:ImageButton ID="btnBack" runat="server" ImageUrl="/assets/back_button.jpg"  OnClick="btnBack_Click" /> 
 <asp:ImageButton ID="btnNext" runat="server" ImageUrl="/assets/next_button.gif" OnClick="btnNext_Click" />
 <asp:ImageButton ID="btnSubmit" runat="server" ImageUrl="/assets/submit_button.gif" OnClick="btnSend_Click" />

Code behind....

protected void btnBack_Click(object sender, EventArgs e)
    {
        MultiView2.ActiveViewIndex--;
    }

    protected void btnNext_Click(object sender, EventArgs e)
    {
        MultiView2.ActiveViewIndex++;
    }

    protected void btnSend_Click(object sender, EventArgs e)
    {
        OnSubmitClicked(e);
    }

Ok more code...

protected override void OnLoad(EventArgs e)
{
        base.OnLoad(e);
     PopulateSomeField();
    }

protected override void OnPreRender(EventArgs e)
    {
        btnBack.Visible = MultiView2.ActiveViewIndex > 0;
        btnNext.Visible = MultiView2.ActiveViewIndex < MultiView2.Views.Count - 1;
        btnSubmit.Visible = MultiView2.ActiveViewIndex == MultiView2.Views.Count - 1;
        base.OnPreRender(e);
    }

There's no error there. It works just fine for me.
