Thanks for your answers.
First I try:
sXef.$("xef").on("click", function(){
alert("Hola" + fXefs[i].nom);
});
but:
Uncaught TypeError: Cannot read property 'nom' of undefined
And after I tried:
var nom = fXefs[i].nom;
sXef.$("xef").on("click", function(){
alert("Hola " + nom);});
but when click on any chef then show the name of the last chef of For loop (the last of array)!
The problem for to make custom events for every instance using variables is not solved yet.
And I have problem accessing to elements inside instances with custom code events, if I try:
sXef.$("xef").on("click", function(){
sXef.$("dates").css("display","block"); //nothing happens
sXef.$("nom").html("hola"); //nothing happens
alert("Hola"); //work
});
nothing happens and no errors in console, for to reference elements inside is not necessary something like this or parent? all other things outside events work perfectly, the symbol instance are created and with the For loop I change photo and name dynamically without problems.
