title: How to get current sort field in kendo grid?
body: <p>I'm beginner... 
  I'm using kendo-grid with Jquery.</p>
  
  <p>I want to get current sorted field in kendo-gird.</p>
  
  <p>I found this.
  console.log(grid.dataSource._sort[0].dir);
  console.log(grid.dataSource._sort[0].field);</p>
  
  <p>Can I find alternative way?</p>
  
  <p>this is my code.</p>
  
  <pre><code>        var dataSource = new kendo.data.DataSource({
          transport       : {
              read        : {
                  type        : 'post',
                  dataType    : 'json',
                  contentType : 'application/json;charset=UTF-8',
                  url         : cst.contextPath() + "/watcher/kendoPagination_statsErrorHistoryRetrieveQry.htm",
                  data        : param
              },
              parameterMap: function (data, opperation) {
                  return JSON.stringify(data);
              }
          },
          schema          : {
              data    : function(data) {
                  return data;
              },
              total   : function(response) {
                  return response.length &gt; 0 ? response[0].TOTAL_COUNT : 0;
              }
          },
          pageSize        : cst.countPerPage(),
          serverPaging    : true,
          serverSorting   : true
      });
  
      var columns = kendoGridColumns();
  
      $("#grid")
          .kendoGrid({
              dataSource  : dataSource,
              sortable    : {
                  mode : 'multiple',
                  allowUnsort : true
              },
              columns     : columns.error()
              selectable  : 'row',
              scrollable  : true,
              resizable   : true,
          }));
  </code></pre>
