How to use the backgrid.Grid function in backgrid

onShow: function () {

    // TODO attach filter state to collection, and restore filter values
    // in the interface on creating the view
    var filterView = new FilterView();

    this.listenTo(filterView, 'search', function (filter) {
      this.collection.state.currentPage = 1;
      _.extend(this.collection.queryParams, filter);
      this.collection.fetch();
