Knockout OptionsAfterRender没有运行

Question

我试图在optionsAfterRender事件之后运行一些代码，但我的函数createPortfolioMultiselect没有被调用且没有错误。

<select id="PortfolioSelector" data-bind="options: listEntities, optionsText: 'name', optionsValue: 'id', optionsAfterRender: createPortfolioMultiselect, value: selectedPortfolio, event: { change: portfolioChanged }"></select>

mViewModel = {
                selectedPeriod: ko.observable(),
                listPeriods: ko.observableArray(),
                selectedPortfolio: ko.observable(),
                selectedPortfolioText: ko.observable(),
                listEntities: ko.observableArray(),
                periodChanged: function (pContext) {
                    // do some work
                },
                portfolioChanged: function () {
                    // do some work
                },
                createPortfolioMultiselect: function (option, item) {
                    // do some work here
                },
                LastRunReports: ko.observableArray()
            };

我使用的旧版淘汰赛2.2.1不支持此功能。用户错误。
