send string from controller to view

I'm just starting out on some ember.js, and am pretty inexperienced. This is probably a very simple question to answer but I can't seem to get it to work. I'm in the controller for my chart trying to set range using 

    range: function() {
    var dataArr = this.get("rawData");
    if (!dataArr) return;
    var range = "";
    var xmax = -1 * Infinity;
    var xmin = Infinity;
    var ymax = -1 * Infinity;
    var ymin = Infinity;

    code to figure out xmin, max etc......

    lowerBound = new Date(xmin)
    upperBound = new Date(xmax)
    range = d3.time.format.utc("%a, %b%e %-I:%M %p")(lowerBound) + " - " + d3.time.format.utc("%a, %b%e %-I:%M %p")(upperBound);
    return range
  }.observes('display', 'rawData'),

I then try to use this with handlebars {{range}} and it does not work... I dont know if I'm providing enough info but if anyone can help out its much appreciated, thank you!

You need to identify your range property as a property, thusly:

range: function() {
    var dataArr = this.get("rawData");
    // blah blah, your implementation
    return range;
  }.property('rawData'),

By specifying rawData as a dependency, Ember will automatically recompute range if rawData changes.
