How to use the geojs.mapInteractor function in geojs

_createMap: function (bounds, tileWidth, tileHeight, sizeX, sizeY) {
        if (this._map) {
            // reset bounds query parameter on map exit
            router.setQuery('bounds', null, {replace: true, trigger: false});
            this._map.exit();
        }
        bounds.left = bounds.left || 0;
        bounds.top = bounds.top || 0;
        tileWidth = tileWidth || (bounds.right - bounds.left);
        tileHeight = tileHeight || (bounds.bottom - bounds.top);
        sizeX = sizeX || (bounds.right - bounds.left);
        sizeY = sizeY || (bounds.bottom - bounds.top);
        var interactor = geo.mapInteractor({
            zoomAnimation: false
        });
        var mapW = this.$el.width() || 100, mapH = this.$el.height() || 100;
        var minZoom = Math.min(0, Math.floor(Math.log(Math.min(
                (mapW || tileWidth) / tileWidth,
                (mapH || tileHeight) / tileHeight)) / Math.log(2))),
            maxZoom = Math.ceil(Math.log(Math.max(
                sizeX / tileWidth,
                sizeY / tileHeight)) / Math.log(2));

        var mapParams = {
            node: '<div style="width: 100%; height: 100%">',
            width: mapW,
            height: mapH,
            ingcs: '+proj=longlat +axis=esu',
            gcs: '+proj=longlat +axis=enu',</div>

renderMap: function () {
        if (!this.map) {

                    click: {
                        enabled: true,
                        cancelOnMove: true
                    }
                })
            });
            var interactorOpts = this.map.interactor().options();
            interactorOpts.keyboard.focusHighlight = false;
            this.map.interactor().options(interactorOpts);
            this.map.createLayer(mapSettings.basemap,
                _.has(mapSettings, 'basemap_args')
                    ? mapSettings.basemap_args
                    : {});
            this.uiLayer = this.map.createLayer('ui');
            this.controlsUiLayer = this.map.createLayer('ui');
