I am wanting to add a refresh function to a jQuery plugin so that I can do
$(selector).tooltipster("refresh")
I've been trying to use this https://stackoverflow.com/a/4414356/123415 but without success. This is what I'm trying:
(function($) {
    $.extend(true, $[ "fn" ][ "tooltipster" ].prototype, {
        refresh: function() {
          this._update(this.Content);
        },
    });
})(jQuery);
For reference, the plugin's code declares _update inside of
(function ($, window, document) {
  Plugin.prototype = {
    _update: function() {
      /* update code */
    }
  }
})( jQuery, window, document );
I'm trying to extend tooltipster I think I've included all the necessary code above though.
The problem seems to be that the Plugin's methods are all within Plugin.prototype which I can't seem to access. As it stands, I'm just getting "Cannot set property 'refresh' of undefined" in the console.
Update If I run $.fn.tooltipster.prototype in the console, I get
- $.fn.(anonymous function) {refresh: function}
  + constructor: function () {
  + refresh: function () {
  + __proto__: Object
Implying that I have added refresh somewhere on tooltipster but not where it's meant to be.
