jsgrid returns blank line after update

Question

After giving an update via ajax in jsgrid the line returns blank

controller: {
    loadData: function(filter) {
        var data = $.Deferred();
        $.ajax({
            type: "GET",
            contentType: "application/json; charset=utf-8",
            url: "/app/Play/",
            dataType: "json"
        }).done(function(response) {
            data.resolve(response);
        });
        return data.promise();
    },
    updateItem: function(item) {
        return $.ajax({
            type: "POST",
            url: "/app/Play/change.php",
            data: item,
        });
    },
}

In the return of the url update: /app/Play/change.php

I return the updated record data in a normal json, same as the initial json used in the load
