Bind JSON to DevExtreme datagrid
<p>I have problem with loading data to DevExtreme datagrid. If i trying example, with this example code:</p>

<pre><code>var orders = new DevExpress.data.CustomStore({
    load: function (loadOptions) {
        var deferred = $.Deferred(),
            args = {};
​
        if (loadOptions.sort) {
            args.orderby = loadOptions.sort[0].selector;
            if (loadOptions.sort[0].desc)
                args.orderby += " desc";
        }
​
        args.skip = loadOptions.skip || 0;
        args.take = loadOptions.take || 12;
​
        $.ajax({
            url: "http://js.devexpress.com/Demos/WidgetsGallery/data/orderItems",
            data: args,
            success: function(result) {
                deferred.resolve(result.items, { totalCount: result.totalCount });
            },
            error: function() {
                deferred.reject("Data Loading Error");
            },
            timeout: 5000
        });
​
        return deferred.promise();
    }
});
​
var grid = $("#gridContainer").dxDataGrid({
    dataSource: {
        store: orders
    },
    paging: {
        pageSize: 12
    },
    pager: {
        showPageSizeSelector: true,
        allowedPageSizes: [8, 12, 20]
    },
    columns: [
        "OrderNumber", "OrderDate", "StoreCity", "StoreState", "Employee", {
            dataField: "SaleAmount",
            format: "currency"
        }
    ]
}).dxDataGrid("instance");
</code></pre>

<p>It works, so problem with execute devextreme datagrid i have not problem. But when i want to set datasource to my data, it doesn't work. I have ASP.NET mvc application. One action GetData return data in JSON format. And if i change url to: </p>

<p><code>url:"/Home/GetData"</code>, or <code>url:"localhost:port/Home/GetData/</code>
add: <code>type:"GET"</code>
and change names of columns to name my columns in JSON response.
It doesn't work. But action GetData returns data in JSON format. 
I'm new in this technologies. Is something what i did wrong? I nowhere found in API reference, how to bind JSON data from MVC action, maybe i was wrong searched.</p>
