Use transients domain attributes with Grails

In latest versions of Grails, transient attributes are not binded with form by default. This is the documentation of the bindable constraint. This is how the code would become (you need to add bindable: true):

static transients = ['confirmarPassword'] 

static constraints = {
    password blank: false, password: true, size:5..15, matches:/[\S]+/
    confirmarPassword bindable: true, blank:false, password: true, size:5..15, matches:/[\S]+/, validator:{ val, obj ->
        if (obj.password != obj.confirmarPassword)
            return 'password.dontmatch'
    }
}

Html element content change event

You could add some custom event to see effect change of the content of the element:
You can see this example here at jsFiddle: Html element content change event 
 

Html content

<table>
    <tr>
        <td valign="top">
           <button id="html">Click to see change 'html'.</button><br/>
           <button id="append">Click to see change 'append'.</button><br/>
           <button id="prepend">Click to see change 'prepend'.</button><br/>
           <div id="hello">This is text!</div>
        </td>
        <td valign="top">
            <div id="console"></div>
        </td>
    </tr>
</table>

jQuery content

// Redefines $.fn.html(), $.fn.append(), $.fn.prepend() to add custom events that are triggered before and after a DOM element's innerHtml is changed
// html-change-pre is triggered before the innerHtml is changed
// html-change-post is triggered after the innerHtml is changed

(function($) {
    var eventName = 'html-change';
    // Save a reference to the original html, append and prepend function
    $.fn.htmlx = $.fn.html;
    $.fn.appendx = $.fn.append;
    $.fn.prependx = $.fn.prepend;
    // Let's redefine the html, append and prepend function to include a custom event
    $.fn.html = function() {
        var currentHtml = this.htmlx();
        if(arguments.length) {

        } else {
            return currentHtml;
        }
    }
})(jQuery);
        
// Test
jQuery(document).ready(function() {

    jQuery('#hello').bind('html-change-pre', function() {
