Problem when resize viewport, width & formatting value about jquery-knob HOT 1 OPEN

Hi! I updated your jsfiddle https://jsfiddle.net/bf8aLtwj/18/ with this approach:

• separate the main format function from optons:
  var format = function(v) { var sec = parseInt(v)*60; var min = Math.floor(sec / 60); sec -= min * 60; return min + ':' + (sec < 10 ? "0" + sec : sec); };

• then I call at draw event instead of format hook:
  `
  $('#knob1').knob({
  'min': 0,
  'max': 60,
  'width': '100%',
  'step': 1,
  'thickness': 0.3,
  'fgColor': '#06BABC',
  'bgColor': '#333',
  'draw': function(){
  this.i.val(format(this.cv));
  }
  });

`

from jquery-knob.
