Webix Jet scope in ajax

Hi!
I use some objects in separate files to support application logic. For example:

define([], function(){
  return {
    name:"",
    getPetName: function(id){
         webix.ajax().post("server/pets.php?cmd=get-name", {id: id},
		webix.bind(function(text, data){
			var response = data.json();
			this.name = response.name;
		}
	), this);
    }
  }
}

But the assignment of the value of the variable “name” does not occur, because scope in this case - “window”.
How to solve the problem of accessing variables from a query and calling the functions of this object?
