Javascript event in renderUI after the DOM has actually rendered

Hi Pierre,

I can confirm the race case situation. I'll bring it up with the shiny team later today.

I was able to get around the event race case by wrapping the console.log and sparkline calculations in a setTimeout(update, 0).

$(function() {

  // trigger redraw of sparklines after each event value
  $(document).on({
    'shiny:value': function(event) {
      if (event.name === 'tbl') {
        // defer to next tick to add sparklines
        setTimeout(function() {
          console.log($('.spkln').length);
          $('.spkln').sparkline('html', {type: 'bar', barColor: 'red'});
        }, 0)
      }
    }
  });
});

Hope this helps!

Best,
Barret
