How it works

When callbacks outside of Mithril run, you need to notify Mithril's rendering engine that a redraw is needed. External callbacks could be setTimeout/setInterval/requestAnimationFrame callbacks, web socket library callbacks, event handlers in jQuery plugins, third party XHR request callbacks, etc.

To trigger a redraw, call m.redraw(). Note that m.redraw only works if you used m.mount or m.route. If you rendered via m.render, you should use m.render to redraw.

You should not call m.redraw from a lifecycle method. Doing so will result in undefined behavior.
