Reconstructing segments when the donut data changes

This restores functionality to the donut, which is currently broken on Live. I'm not sure how this was ever working updating the view when the data changes, but my guess is that the callers were destroying and recreating the component whenever the data changed, avoiding this issue. I would imagine it's better practice to not require this.
