javascript - Callback function after tooltip / popover is created with twitter bootstrap?

I want to manipulate a tooltip or popover after it is created with twitter bootstrap. As far as i know there isn't a build in way to do this.

$('#selector').popover({
  placement: 'bottom'
});

For example lets say i want to move the created tooltip up 5px and left 5px from it's calculated location. Any ideas on the best way to do this?

This is what i'd like to do:

$('#selector').popover({
  placement: 'bottom',
  callback: function(){
    alert('Awesome');
  }
});

Works for tooltip:

var tmp = $.fn.tooltip.Constructor.prototype.show;
$.fn.tooltip.Constructor.prototype.show = function () {
  tmp.call(this);
  if (this.options.callback) {
    this.options.callback();
  }
}

this.$('#selector').tooltip({ 
  placement: 'top', 
  callback: function() { 
    alert('hello') 
  } 
});
