        },

Answer 1

If you registered some event handler on some element using on() method, then you can simply remove it using off()

 $(document).on('updateSelection', this.beforeStartSelect.bind(this));
 $(document).on('suspendSelection', this.suspendSelection.bind(this));

just update your suspendSelection() like this,

suspendSelection : function(){
   /* select the same element, call off() passing the event to 
      remove and the handler function you used while registering*/
   $(document).off('updateSelection', this.beforeStartSelect.bind(this));
}

Hope this helps :)
