Add text before / after a textbox

I've used the following Javascript to add custom text before or after a input textbox in an answer so far:

Qualtrics.SurveyEngine.addOnload(function()
{
var inputs = $(this.getQuestionContainer()).select('input[type="text"]');

for (var i = 0; i < inputs.length; i++) {
var input = inputs[i];

$(input).insert({before: 'text'});
$(input).insert({after: 'text'});
}

});

Now it seems that is not longer working :-(
Has anybody an idea how it could be working now?
I'm not really a Javascript-crack...
