title: Passing two params to sub-level treeview with HierarchicalDataSource
body: <p>How can I send 2 params to sub-level treeview.</p>
  
  <p>Sample:</p>
  
  <pre><code>var data2 = {
    transport: {
      read: {
        url: function(options) {
          console.log(options);
          return kendo.format("/url2/", [options.param1, options.param2]);
        },
        dataType: "jsonp"
      }
    },
    schema: {
      model: {
        id: "param4",
        fields: {
          param4: {type: "number"},
          param5: {type: "string"},
        },
        hasChildren: "param4",
      }
    }
  };
  var data1 = new kendo.data.HierarchicalDataSource({
    transport: {
      read: {
        url: "/url/",
        dataType: "jsonp"
      }
    },
    schema: {
      model: {
        id: "param1",
        fields: {
          param1: {type: "number"},
          param2: {type: "number"},
          param3: {type: "string"},
        },
        hasChildren: "param1",
        children: data2
      }
    }
  });
  
  $("#treeview").kendoTreeView({
    dataSource: data1,
    dataTextField: ["param3", "param5"]
  });
  </code></pre>
  
  <p>When I debug code with <code>console.log(options);</code> only params that pass is <code>param1</code>.
  How I can get <code>param2</code>?</p>
  
  <p>There is no sample or documention at <a href="http://demos.kendoui.com/web/treeview/remote-data.html" rel="nofollow">KendoUi Demos</a>, is there a easy way or I must just log all select path for this?</p>
