-
-  onEnabled: function(bounds) {
-    // do something with the the filter bounds
-  },
-
-  onDisabled: function(bounds) {
-    // do something with the the filter bounds
-  }
-}).addTo(map);

+```javascript
+locationFilter.on("change", function (e) {
+    // Do something when the bounds change.
+    // Bounds are available in `e.bounds`.
