在IE9中没有调用select元素的内联处理程序

我正在尝试找出在生产机器上可能导致IE9出现问题的原因。我们有一个<select>组合框与一个内联的变化处理程序(我知道这是不好的做法，但我不能做任何关于那时刻)，没有被调用。

HTML看起来像下面(从开发工具复制)

<select name="propertyName" id="propertyName" onchange="Workflows.CoreSetPropertyActivity._field_OnChange();">
  <option value="Property_103156" title="Boolean Prop" selected="selected">Boolean Prop</option>
  <option value="Property_103072" title="String Prop A">String Prop A</option>
</select>

在与客户的webex上，我在Workflows.CoreSetPropertyActivity._field_OnChange()中放置了一个断点，它没有被调用(在IE9中)。如果我在控制台中手动调用它，一切都可以正常工作。

我们使用IE8和Workflows.CoreSetPropertyActivity._field_OnChange()的完全相同的机器，并且一切正常工作。

我认为唯一相关的信息是下拉菜单是动态创建的。

有人遇到类似的东西吗?有什么建议可以试试吗?也许IE中的一些设置可以打破这个魔咒?

创建HTML

使用以下代码将选择添加到页面中。要插入的HTML看起来像

<div class="wrapper">
    <ul id="setStateConditions">
        <li class="setStateLabel">Property Name</li>
        <li class="setStateContent">
            <select name='propertyName' id='propertyName'  onchange='Workflows.CoreSetPropertyActivity._field_OnChange();' >
<option value='Property_103156' title='Boolean Prop'  selected='selected' >Boolean Prop</option>
<option value='Property_103072' title='String Prop A' >String Prop A</option>
</select>
