How can I temporarily disable the onclick event listener, (jQuery preferred), after the event has been fired?

Example:

After the user clicks on the button and fires this function below, I want to disabled the onclick listener, therefore not firing the same command to my django view.

$(".btnRemove").click(function(){
   $(this).attr("src", "/url/to/ajax-loader.gif");
   $.ajax({
        type: "GET",
        url: "/url/to/django/view/to/remove/item/" + this.id,
        dataType: "json",
        success: function(returned_data){
            $.each(returned_data, function(i, item){
              // do stuff                       
     });
   }
});

Thanks a lot,

Aldo
