这里有剑道 UI 的新手，感谢您的帮助。网格弹出编辑器窗口中的选定列表视图出现问题。
它显示并且是可选择的，但我无法将选定的列表视图数据发送到 JSON 字符串
发送到服务器的 json 字符串：
{"blog"=>{"id"=>"", "title"=>"New title", "content"=>"New content", "published"=>"", "img_name"=>""}}
我的代码，kendo-grid 和 kendo-listview：
<script type="text/x-kendo-tmpl" id="image_template">
<div class="product">
<img src="/assets/blog/${img_name}" width="100" />
</div>
</script>
<!-- popup editor template -->
<script id="popup_editor" type="text/x-kendo-template">
<form class="form-horizontal">
<div class="control-group">
<label class="control-label" for="title">Title</label>
<div class="controls">
<input type="text" id="title" name="Title" data-bind="value:title">
</div>
</div>
<div class="control-group">
<label class="control-label" for="published">Published</label>
<div class="controls">
<input type="checkbox" id="published" data-bind="checked: published" />
</div>
</div>
<textarea id="editor" name="content" data-bind="value:content"></textarea>
<div id="listView"></div>
<div class="control-group">
<label class="control-label" for="img_name">Image Name</label>
<div class="controls">
<input type="text" id="img_name" name="img_name" data-bind="value: img_name"/>

我可以通过输入文本成功发送img_name数据
<input type="text" id="img_name" name="img_name" data-bind="value: img_name"/>
但是我无法使用 listview 中的 onChange 函数对其进行更改
对此有什么想法吗？
