title: How do you force Ember to rerender a component?
body: <p>I have an Ember component that uses jQuery to add a canvas chart.  When I change routes, I get a new model, but Ember's automatic rerendering does not work in this case.  In fact, I don't know how to make the component code which adds the chart re-run at all.  How can I do this?</p>
  
  <p>Would it work better if it was a view?</p>
