How can I add event listener only for THIS object instance

Question

I've got a basic jQuery plugin. This plugin can have multiple instances.

The problem: every time new instance is created, a click event will fire in all instances. I just want to limit the event to one particular instance. Your answer would be much appreciated.

(function($){

  if(!$.SQ){
      $.SQ = new Object();
  };

  $.SQ.Check = function(options){

    function sayhi() {
      alert('HI');
    };

    this.localhi = new sayhi();

    $( "#PhoneSQNewConnectBtn" ).bind( "click", function() {
      this.localhi = new sayhi();
    });

};

})(jQuery, window, document);

// Create multiple instances
this.generateNewNumber1 = new $.SQ.Check();
this.generateNewNumber2 = new $.SQ.Check();
this.generateNewNumber3 = new $.SQ.Check();

As Arun P Johny mentioned it's not the best idea to put event listeners inside a plugin which gets instantiated.
