Conditionally change link color?

I am attempting to change link colors in my GoJS tree depending on a key / value pair in my model data (color, in this case). I am attempting to call my method to change the link color by doing the following:

  myDiagram.linkTemplate =
    $(go.Link,
      { routing: go.Link.Orthogonal, corner: 5, toShortLength: -2, fromShortLength: -2 },
      $(go.Shape, { strokeWidth: 2, stroke: colors["gray"] },
      new go.Binding("geometry", "color", setLinkColor))); // the link shape and color

However, my setLinkColor method is never called. Here it is for reference:

  function setLinkColor(color) {

    console.log("value of color: ", color);

    switch(color) {

      case "critical":
        link = go.Shape.stroke(colors["orange"]);
        break;
      
        
      default:
        link = go.Shape.stroke(colors["white"]);

    } 
    return link;   
  }

How can I conditionally color my Links depending on the value of color?
