Why not use jQuery shorthands for ajax requests?

index.js.jsx

  filterNetworks(value) {
    $.ajax({
      url: this.props.url,
      data: {
        network: network,
        page: pageNumber||1,
        search: search
      },
      dataType: 'json',
      success: function (carts) {
        this.setState({data:carts});
      }.bind(this),
      error: function (xhr, status, err) {
      }.bind(this)
    });
  }
