title: Can i use a function name in my jquery plugin parameters?
body: <p>I am creating a form validation plugin for jQuery and would like it to call a function once the form has been successfully validated.
  The plugin will have a default callback function, but I would like to modify this through the options parameter. 
  Unfortunately what i have (below) does not work. Any ideas?</p>
  
  <pre><code>(function($){
      $.fn.extend({
          validify : function(options) {
              var defaults = {
                  callback: "callbackFunc",
              };
  
              var options = $.extend(defaults,options);
  
              return this.each(function(){
                  //validation code here
                  //if valid call the function
                  if(errors==0){
                      options.callback;
                  }
  
  
              function callBackFunc(){
                  // the default callback function
              }
  
              ...
  </code></pre>
