Extending editors ?

I saw in documentation that we can create custom editors like that:

webix.editors = {
    "mytext":{
        focus:function(){/*...*/},
        getValue:function(){/*...*/},
        setValue:function(value){/*...*/},
        render:function(){/*...*/}
    }
};

But is it possible to extend existing ones ?

Hi, @michald1986 ,
the method you mentioned is completely wrong and docs should be revised.
check this for preferred method.
existing editors can also be extended this way.
