Toggling draw-control breaks.

[sholsapp]

Assuming example code like the following:

{{#leaflet-map}}
  {{#if showDrawControl}}
    {{draw-control}}
  {{/if}}
{{/leaflet-map}}

I've found that if you toggle the property showDrawControl above, to hide/unhide the controls, that the controls are drawn multiple times, and no longer become usable (it seems that they lose a reference to the original map).

Is this a bug in ember-leaflet-draw, or something else? Anyone have any examples of toggling functionality of draw controls?
