Legend for Clustergrammer JS doesnt get updated on Defining Custom Tile Colors

[mayankmusaddi]

When the tile_colors field in the argument was set to a different color, the heatmap generated gets updated however the legend always shows the colors red and blue only as is evident in the image,

Ways to reproduce

var args = {
    root: chartid,
    network_data: data,
    tile_colors: ["#ED9124", "#00FF00"],
  };

cgm = Clustergrammer(args);

When using the above piece of code in a JS file to generate the heatmap, the tile colors gets updated however the legend remains the same.
