title: Leaflet: Update GeoJson filter?
body: <p>I would like to populate a GeoJson layer with data and then dynamically filter what features to show.</p>
  
  <p>I have gotten the filter function to work but I do not know how to change the filter and then refresh the layer.</p>
  
  <p>Is there any way I can update the filter after I have added the data?</p>
