javascript - Grails using submittoremote and onsuccess -

i can't make onsuccess event works... try use data rendered controller doesn't work.

my gsp code:

<g:submittoremote name="supprimerusr" url="[controller:'user',action:'presupprimeruser']" class="submit"      value="${g.message(code: 'liste.user.bouton.supprimer.label')}" update="messageinfoerro" onsuccess="confirmersuppruser(data);"/> 

here method in controller "presupprimeruser":

def presupprimeruser () {     ...     render(status: 200, text: 'haha')     ... } 

javascript method "confirmersuppruser":

function confirmersuppruser(data) {     alert('confirm normal');     alert(data.text + 'haha '+ data.status); } 

whatever try doesn't work, have text render in controller, prints "undefined".

how can make work ? didn't find many documentation it.

thank you
