stateSave doesn´t work with an extra function

tupfer

I use a function for my datatable to show only the data with the status I select. When I additional use statesave, the state of the table will be saved, but no data will be show.
This is my javascript file:

```

$(function () {
fillChart();

function fillChart() {
    $(".chartProportion").each(function () {

        var canvas = $(this);
        var locationId = $(canvas).attr("data-locationId");
        var orderStatus = $(canvas).attr("data-orderStatus");

        $.ajax({
            url: "/Charts/OrdersProportion",
            type: "GET",
            async: true,
            cache: false,
            dataType: "json",
            data: { "locationId": locationId, "orderStatus": orderStatus },
            success: function (chartData) {
                //alert("Operation succesful completed");

                //// Check if all data values are false
                //// if so: then render text instead of the chart
                //var containsOrders = false;
                //for (var i = 0; i < chartData.data.length; i++){
                //    if (chartData.data[i] !== 0) {
                //        containsOrders = true;
                //        break;
                //    }
                //}
                ////alert("ContainsOrders: " + containsOrders);
                //if (containsOrders) {
                //Chart.defaults.global.defaultFontColor = '#fff';

                var data = {
                    labels: chartData.labels,
                    datasets:
                    [
                        {
                            data: chartData.data,
                            backgroundColor: chartData.backgroundColor,
                            hoverBackgroundColor: chartData.hoverBackgroundColor,
                            borderColor: chartData.borderColor,
                            borderWidth: chartData.borderWidth
                        }
                    ]
                };

                var myBarChart = new Chart(canvas, {
                    type: 'bar',
                    data: data,
                    options: {
                        title: {
                            text: "Nach Prioritäten",
                            position: "left",
                            display: true
                        },
                        legend: {
                            display: false,
                            position: "right"
                        },
                        scales: {
                            yAxes: [{
                                ticks: {
                                    min: 0

                            }]
                        }
                    }
                });
                //} else {
                //    alert("IN ELSE STATEMENT");
                //    var flaeche = $(this);
                //    alert("FURTHER ON");
                //    var ctx = flaeche.getContext("2d");
                //    ctx.font = "50px Arial";
                //    ctx.fillText("NONE", 10, 10);
                //    alert("have come to the end");
                //}
            },
            error: function (err) {
                alert("An Error occured during the operation" + err.statusText);
            }
        });
    });
