Carousel bootstrap problem with asp events resets the slide

Hi, I'm using the bootstrap carousel in asp, which contains several repeaters. Which in turn launch events. The problem I have is that when going to the server when launching an event, the slide is being changed to the first one that was generated.

I leave the example and what I have tried:

<div class="carousel slide media-carousel" id="media">
 <div class="carousel-inner">
  <asp:Repeater ID="rptGruposEntradas" OnItemDataBound="rptGruposEntradas_ItemDataBound" runat="server">
<ItemTemplate>
 <div id="divSlide" class="item <%#If(Container.ItemIndex = hdSliderSelect.Value, "active", "") %>">
  <div class="col-md-12">                                                                          
   <div class="ticket type-ticket-uno">                                                                               
    <asp:Label ID="lnkGrupoInternet" CssClass="tituloGrupoInternet clic-active" 
    runat="server"></asp:Label>                                                                              
    <asp:HiddenField ID="hdGrupoInternet" runat="server" />                                                                              
    <asp:HiddenField ID="hdSliderPosition" runat="server" />

I have tried to modify the hidden I use to control the initial slide when loading the page, but it has not worked

<%#If(Container.ItemIndex = hdSliderSelect.Value, "active", "") %>"


 Protected Sub btnMas_Click(sender As Object, e As EventArgs)
        Dim boton As Control = sender
        Dim hdSliderPosition As HiddenField = boton.Parent.Parent.Parent.FindControl("hdSliderPosition")
        txtCantidad.Text = txtCantidad.Text + 1
        hdSliderSelect.Value = hdSliderPosition.Value
        CargarFocoGrupoEntrada(sender)
    End Sub

I have also tried to manually search the current slide and put the class="active" , but I have not been able to solve it either.

 Private Sub CargarFocoGrupoEntrada(control As Object)
        'Obtenemos el RepeaterItem padre, el RepeaterItem del grupo y el repeater de recintos
        Dim itemEntrada As RepeaterItem = BuscarRepeaterItemPadre(control)
        Dim itemGrupoEntrada As RepeaterItem = BuscarRepeaterItemPadre(itemEntrada)
        Dim hdGrupoInternetActual As HiddenField = BuscarHiddenHijo(itemGrupoEntrada, "hdGrupoInternet")
        'Recorremos los recintos
        For Each itemGrupo As RepeaterItem In rptGruposEntradas.Items
            Dim hdGrupoInternet As HiddenField = BuscarHiddenHijo(itemGrupo, "hdGrupoInternet")
            Dim divSlide As HtmlControl = BuscarHtmlGenericHijo(itemGrupo, "divSlide")
            If hdGrupoInternet.Value.Equals(hdGrupoInternetActual.Value) Then
                divSlide.Attributes()("class") = "active"
            Else
                divSlide.Attributes()("class") = ""
            End If
        Next
    End Sub
