in the console?

and check to see if blurring the field calls alert?

also did you inspect the dom (elements tab) to see if a input with id field was ever created?

I'll assume you can see n number of input fields on screen!

also I was wrong before not sure about jQuery but ExtJS does not like a # for id's it can be removed for desired effect

Ext.onReady(function() {
Ext.get('#i_numero_factura').on('blur', function() {
alert('Handler for .blur() called.');
});
});
I dont think the problem is on my function jquery, because i created a form in html calling the same function and is working, i remove # but still doesnt work...
