JQuery - TaxonomyFieldControl changed

In some case I needed to catch a event if TaxonomyFieldControl was changed.
The solution was here.
So, I added a plugin to my .js file


jQuery.fn.contentChange = function(callback){
 var elms = jQuery(this);
 elms.each(
   function(i){
var elm = jQuery(this);
elm.data("lastContents", elm.html());
        window.watchContentChange =                                                                            window.watchContentChange 
               ? window.watchContentChange : [];
window.watchContentChange.push({"element": elm, "callback": callback});
                })
return elms;
}
setInterval(function(){
   if(window.watchContentChange){
       for( i in window.watchContentChange){
     if(window.watchContentChange[i].element.data("lastContents")!=
         window.watchContentChange[i].element.html())
        {
          window.watchContentChange[i].callback.apply(window.watchContentChange[i].element);
 window.watchContentChange[i].element.data("lastContents",
 window.watchContentChange[i].element.html())
};
  }
  }
},500);

...and in the end I put this code to watch it.


$('div#taxonomyName').contentChange(function(){

//TO DO
});
