Backbonejs を使用してグリッドをデータで埋める BackgridJs を使用しています。

これは私のコードが今どのように見えるかです:

    var Territory = Backbone.Model.extend({});

var Territories = Backbone.Collection.extend({
  model: Territory
  //url: "examples/territories.json"
});

//var territories = new Territories();
var territory1 = new Territory({ name: "How Bizarre", pop: 20 });
var territory2 = new Territory({ name: "How ", pop: 21 });
var territories = new Territories([territory1,territory2]);
var columns = [{
  name: "id", // The key of the model attribute
  label: "ID", // The name to display in the header
  editable: false, // By default every cell in a column is editable, but *ID* shouldn't be
  // Defines a cell type, and ID is displayed as an integer without the ',' separating 1000s.
  cell: Backgrid.IntegerCell.extend({
    orderSeparator: ''
  })
}, {
  name: "name",
  label: "Name",
  // The cell type can be a reference of a Backgrid.Cell subclass, any Backgrid.Cell subclass instances like *id* above, or a string
  cell: "string" // This is converted to "StringCell" and a corresponding class in the Backgrid package namespace is looked up
}, {
  name: "pop",
  label: "Population",
  cell: "integer" // An integer cell is a number cell that displays humanized integers
}, {
  name: "percentage",
  label: "% of World Population",
  cell: "number" // A cell type for floating point value, defaults to have a precision 2 decimal numbers
}, {
  name: "date",
  label: "Date",
  cell: "date",
}, {
  name: "url",
  label: "URL",
  cell: "uri" // Renders the value in an HTML anchor element
}];

// Initialize a new Grid instance
var refreshgrid = function(){
    var grid = new Backgrid.Grid({
      columns: columns,
      collection: territories
    });

    // Render the grid and attach the root to your HTML document
    $("#example-1-result").append(grid.render().$el);
}
// Fetch some countries from the url
//territories.fetch({reset: true});


    $(".dropdown-menu li").click(function(){
    $(this).closest('.btn-group').children('a').text($(this).text())
});

    $('#submit').on('click', function(event) {
        url = '/ledger/data'
        company_code = $("#company_code").text();

 // event.preventDefault(); // To prevent following the link (optional)
 $.post( url, { name: "John", time: "2pm" },function(data){
    ledgerData = JSON.parse(data);

    refreshgrid();
 });
      //$.post(url,function(response){
      //  alert(response);
      //});
});
    </script>
  </body>
</html>

Post リクエストで JSON データを取得すると、refreshgrid() 呼び出し中にそれをグリッドにフィードする方法がわかりません。

ほとんどの Backbonejs の例では、url はモデル自体にありますが、私にとっては、送信するたびに URL が変化し続けます。では、データを取得してグリッドにフィードするにはどうすればよいでしょうか。
