重复点击input#e和input#c，Singleoption的参数为什么会一直累加，不懂原理，求解

//html
     
     
    

//js
 $('#e').live('click', function(e) {
        $(this).Singleoption({
            column: 1,
            Bound: "#e"
        });
        e.stopPropagation();
    });
    $('#c').live('click', function(e) {
        $(this).Singleoption({
            column: 2,
            Bound: "#c"
        });
        e.stopPropagation();
    });
    $.fn.Singleoption = function(options) {
        var defaults = {
            column: 1,
            Bound: ""
        };
        var options = $.extend({}, defaults, options);
        var a = function() {
            console.log("this a()");
        }
        var b = function() {
            console.log("this b()")
        }
        switch(options.column) {
            case 1:
                a();
                break;
            case 2:
                b();
                break;
        }
        $("body").on("click", "#v", function(e) {
            console.log(options.Bound);
        })
    }
