Clean and display a table depending on the selected client of a Dropdowlist?

I have a dynamic table that I paint by means of Javascript, only that I have a problem when selecting the client in the DropDownList, it shows me the table, and if I change the client I insert the lines in the same table, I would like it to select another client the table will be cleaned and I will only insert the lines of the selected client !!!

 SelectedClient: function () {


    InventarioE.ClienteId = $("#ClienteId").val();
    InventarioE.FechaInventario = $("#FechaTxt").val();
    Inventario.getInventario();
},



//Obtiene la información para la tabla de inventarios
getInventario: function () {
    General.ajax({
        url: InventarioE.uriInventario,
        data: {
            ClienteId: InventarioE.ClienteId, Fecha: InventarioE.FechaInventario, Proceso: InventarioE.proceso
        },
        type: Method.Post,
        Callback: Inventario.CallBackGetListaInventarios
    });
},

CallBackGetListaInventarios: function (data) {
    var dta = data.aaData.Model;
    Loading.ShowLoader();

    InventarioE.tblInventarioId.destroy();


    if (dta != null)
        dta.forEach(Inventario.InsertaRenglon)

    InventarioE.tblInventarioId = $('#tbInventarioId').DataTable(

        {

            language: Grid.languageDefault,

            dom: 'ft<"lengt"l><"info"i><"pagination"p>',

        });
    Loading.HideLoader();



    console.log(data);
},

//Metodo para dibujar tabla
InsertaRenglon: function (item, index, arr) {
    var table = document.getElementById("tblInventarioId");
    var row = table.tBodies[0].insertRow();
    row.id = "tc" + item.NumeroDeParte;
    var cell0 = row.insertCell(0);
    var cell1 = row.insertCell(1);
            var cell2 = row.insertCell(2);
    var cell3 = row.insertCell(3);
    var cell4 = row.insertCell(4);



    cell0.innerHTML = item.Descripcion;
    cell1.innerHTML = item.NumeroDeParte;
    cell2.innerHTML = item.AlmacenId;
    cell3.innerHTML = item.AlmacenDesc;
    cell4.innerHTML = "<input type='text' class = 'form-control input-sm jsTrim jsNumber' name='type' id='txt" +
        item.NumeroDeParte + item.AlmacenId + "' value='" + item.Cantidad + "'style='width:50px '>";
