Problems when querying Data with jQuery.DataTables ()

I am working with jquery.DataTables () in an Mvc application with Asp.Net

I have implemented the data query through ajax, but I have an error and I can not find where it is, since according to the documentation the name of the action result that the data brings me would be badly written.

in the Html I have the following:

<div id="GridInfoProcesos" class="display">
    <table id="TablaProcesos" class="display" style="width:100%">
        <thead>
            <tr>
                <th>Id</th>
                <th>Cliente</th>
                <th>Proceso</th>
                <th>Fecha</th>
                <th>Registros Cargados</th>
                <th>Registros Validados</th>
                <th>Registros Erroneos</th>
                <th>Estado</th>
                <th>Acciones</th>
            </tr>
        </thead>
        <tfoot>
            <tr>
                <th>Id</th>
                <th>Cliente</th>
                <th>Proceso</th>
                <th>Fecha</th>
                <th>Registros Cargados</th>
                <th>Registros Validados</th>
                <th>Registros Erroneos</th>
                <th>Estado</th>
                <th>Acciones</th>
            </tr>
        </tfoot>
    </table>
</div>

The Ajax call is defined as follows:

    <script src="~/Scripts/DataTables/jquery.dataTables.js"></script>
<script type="text/javascript">
    $(document).ready(function () {

        //Invocamos el plug-in DataTable , indicamos que el procesamiento lo realizara a través del servidor,
        //indicamos el método y las columnas que se van a mostrar en nuestra tabla
        $('#TablaProcesos').DataTable({
            "processing": true,
            "serverSide": true,
            "ajax": "Proceso/GetProcesosKamCliente",
            "columns": [
                { "data": "Id" },
                { "data": "Cliente" },
                { "data": "Proceso" },
                { "data": "Fecha" },
                { "data": "Cargados" },
                { "data": "Validados" },
                { "data": "Erroneos" },
                { "data": "Estado" },
                { "data": "Acciones" }
            ]
        });
    });



</script>

and finally in the controller I have the following Action Result:

        public ActionResult GetProcesosKamCliente(DataTableRequest model)
    {
        DataTableAdapter<VM_ProcesosCliente> result = new DataTableAdapter<VM_ProcesosCliente>();

        string sKamId = "1";
        string sClienteId = "1";
        int KamId = Convert.ToInt32(sKamId);
        int ClienteId = Convert.ToInt32(sClienteId);

        // obtiene los datos dessde la BD
        TW.Business.Kam.Proceso ck = new Proceso();
        List<VM_ProcesosCliente> lstProcesosKamCliente = ck.GetProcesosKamCliente(KamId, ClienteId);


        //Obtenemos el total de registros de la tabla.
        var totalRows = lstProcesosKamCliente.Count();

        Func<VM_ProcesosCliente, Object> orderByFunc = null;
        //El ordenamiento que vamos a utilizar por default va ser por el Id.
        orderByFunc = item => item.Id;

        //Dependiendo de la columna que seleccionemos indicamos si se ordena por el campo Description.
        if (model.order[0]["column"].Equals("1"))
        {
            orderByFunc = item => item.Id;
        }

        //Obtenemos el valor a buscar.
        var searchValue = "" + model.search["value"] + "";

        var queryItem = lstProcesosKamCliente.Where(d => d.Proceso.Contains(searchValue));
        List<VM_ProcesosCliente> items;
        //Indicamos cual va ser la manera en que se van a ordenar los datos.
        if (model.order[0]["dir"].Equals("desc"))
        {
            items = queryItem.OrderByDescending(orderByFunc).Skip(model.start + 1).Take(model.length).ToList();
        }
        else
        {
            items = queryItem.OrderBy(orderByFunc).Skip(model.start + 1).Take(model.length).ToList();

        }

        //Llenamos con información nuestro DataTableAdapter
        result.Data = items;
        result.Draw = model.draw;
        result.RecordsTotal = totalRows;
        result.RecordsFiltered = queryItem.Count();
        //Regresamos la respuesta Json
        return Content(JsonConvert.SerializeObject(result), "application/json");

    }

The error that appears in the debugger of Crome, is 404 (not Found)

Could someone please give me a hand with this topic? I have given it many laps, but I can not find a solution. Thanks for reading.
