Test blocked with CasperJS - casperjs

Question

This is my code:
casper.then(function() {
this.click('.btn-attendee');
this.waitForSelector(
'#form_signup2',
function() {
this.wait(3000, function() {
//El parametro 'INFO' es para que el echo aparezca en color VERDE
this.echo('Existe el popup SIGNUP', 'INFO');
this.capture('signup.jpg', undefined, {
format: 'jpg',
quality: 75,
});
this.echo('pantallazo signup', 'INFO');
this.wait(4000, function() {
this.fill('form#form_signup2', {
'first_name': 'Perico',
'last_name': 'Palotes',
'email': new Date().getTime()+'#testing.es',
'password': '123456'
//Ponemos false porque sino nos haria el SUBMIT del formulario y no queremos eso.
//En el email la pasamos un numero aleatorio para que no de fallo al ejecutar el script varias veces
}, false);
this.evaluate(function() {
document.getElementById('checkbox1').style.display="block";
})
this.click('#checkbox1');
this.wait(1000, function() { this.click('.final_button'); });
this.wait(15000, function() {
this.capture('signup2.jpg', undefined, {
format: 'jpg',
quality: 75,
});
this.echo('pantallazo signup2', 'INFO');
this.wait(1000, function() {
this.echo('Existe el popup del paso2 SIGNUP', 'INFO');
this.wait(2000, function() {
//RELLENAMOS EL FORMULARIO DEL 2º POPUP DE SIGNUP EMAIL
//FORMUARIO FASE 1
this.fill('form#form_step3', {
'user_alias': new Date().getTime()+'Perico',
'town': 'Valencia',
'role': 'uno',
'company': 'testing_company'
//Ponemos false porque sino nos haria el SUBMIT del formulario y no queremos eso.
}, false);
this.wait(2000, function() {
this.capture('form2.jpg', undefined, {
format: 'jpg',
quality: 75,
});
this.echo('pantallazo form2', 'INFO');
//MY PROBLEM
//Here I try to make a this.wait with a this.echo, but if I do get stuck in the test phase ... this.echo('pantallazo signup2', 'INFO')
});
});
});
});
});
});
},
function(){
//El parametro 'ERROR' es para que el echo aparezca en color ROJO
this.echo('error login', 'ERROR')
},
10000
);
});
In the last attempt this.wait I have put in with the other this.wait with this.echo for example, but if I do and I run the script I get stuck here:
this.echo('pantallazo signup2', 'INFO');
That I can do to make this wait another where I have mentioned that the test is not blocked?
