ember.js不会{{bindAttr}} 对于集合中正确的inputField.elementId的attibute(ember.js does not {{bindAttr}} the For attibute to the correct inputField.elementId in a collection)

 我试图使用{{bindAttr}}和输入字段的[viewName] .elementId将标签链接到输入字段。 它在单个条目视图中工作，但不是在显示多条记录时：它只是将标签链接到集合中的最后一个输入字段。 （这个过去在以前的迭代中使用了一个较旧的内部函数库，但现在它没有。）我创建了一个小提琴，但它的要点是： 
 
{{#each controller}}
    <fieldset>              
        <label {{bindAttr for="view.tbFullName.elementId"}}>Full Name</label>
        {{view App.DetailTextField viewName="tbFullName" placeholder="Full Name" valueBinding="fullName" readonly="readonly"}}                              
    </fieldset>
{{/each}}
 
 我想也许我可以创建一个collectionView并为viewName创建一个计算属性，它将为集合中的每个项目生成一个唯一的ID， 这里提到的另一个问题就是提到的。 但是，这样做太复杂了 - 只要用户点击相应的标签，我就可以让输入字段自己突出显示。 
 
 任何帮助赞赏。 

I'm trying to link a label to an input field using the {{bindAttr}} and the input field's [viewName].elementId. It works on a single entry view, but not when there are several records being displayed: it just links the label to the last input field in the collection. (This used to work in a previous iteration using an older ember library but now it doesnt.) I've created a fiddle but the gist of it is:
 
{{#each controller}}
    <fieldset>              
        <label {{bindAttr for="view.tbFullName.elementId"}}>Full Name</label>
        {{view App.DetailTextField viewName="tbFullName" placeholder="Full Name" valueBinding="fullName" readonly="readonly"}}                              
    </fieldset>
{{/each}}
 
I thought maybe I could create a collectionView and create a calculated property for viewName which would generate a unique ID for each item in the collection, sort of mentioned in answer to another problem here. But that is getting WAY too complicated - just so that I can have the input field highlight itself if the user clicks on the corresponding label.
 
Any help appreciated.
