jQuery找不到动态元素

我让jQuery处理我的许多其他动态元素，包括来自同一分部的元素，但我似乎无法通过下面显示的名称或id访问这些元素。

为了尝试访问元素，我经历了许多jQuery选择器，但在这个实例中没有一个有效，我不知道为什么。

我已经尝试了[name=$'value']、[name~='value']以及下面代码中显示的那个（在我的另一个代码中也以类似的身份工作）和fiddle（[name*='value']），但没有找到这些元素。

这是什么原因/我应该做什么或不应该做什么？

下方代码

将cshtml呈现为HTML标记：

<div class="ui-grid-c ui-responsive">
    <div class="ui-block-a">
        <p class="lblStyle">Size(CIDR) *</p>
    </div>

带有通配符选择器的JQuery：

function pad(n, width, z) {
    z = z || '0';
    n = n + '';
    return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
}
$("input[name*='requestedIpCidr']").change(function () {
    var prefix = $(this).val();
    var zeros = pad(0, 32 - prefix, 0);
    if (32 - prefix == 0) zeros = '';
    var full = pad(zeros, 32, 1);
    var octets1 = full.substring(0, 8);
    var octets2 = full.substring(8, 16);
    var octets3 = full.substring(16, 24);
    var octets4 = full.substring(24, 32);
    var o1 = parseInt(octets1, 2).toString(10);
    var o2 = parseInt(octets2, 2).toString(10);
    var o3 = parseInt(octets3, 2).toString(10);
    var o4 = parseInt(octets4, 2).toString(10);
    $(this).nextAll("input[name*='requestedIpMask']").first().val(o1 + '.' + o2 + '.' + o3 + '.' + o4);
});
