checkbox checked is not changing the data in repeater's footer template

I have a data for boolean control in repeater for checking. I created a footer template for sum price total in checked and unchecked items. But I only get all total of prices.linq query is qorking but checkbox is not firing in repeater footer even checkedbox change event changes the checked. How can I fix that issue?

 string durum;

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            loadFirmaOdemeler();
        }
    }    
 
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Footer)
    {
        var data = (DataRowView)e.Item.DataItem;

        var checkOnaySonuc = (e.Item.FindControl("checkOnaySonuc") as Label);
        if (string.IsNullOrEmpty(durum))
        {
            total = callFirma().AsEnumerable()
            .Sum(r => Convert.ToDouble(r["odemeTutari"]));
        }
        else
        {
            if (durum.Equals("1"))
            {
                total = callFirma().AsEnumerable()
                .Where(r => r.Field<string>("odemeOnayi") == "1")
            .Sum(r => Convert.ToDouble(r["odemeTutari"]));
            }
            else
            {
                total = callFirma().AsEnumerable()
                .Where(r => r.Field<string>("odemeOnayi") == "0")
            .Sum(r => Convert.ToDouble(r["odemeTutari"]));
            }
        }
    }
}

 protected void onaylandıGosterCheck_CheckedChanged(object sender, EventArgs e)
    {
        var chck = (CheckBox)sender;
        string durum = chck.Checked ? "1" : "0";
    }
