数据更改时模板的流星助手不触发？

Question

I have the following on my client side:

Template.cellular.helpers({
    getCells: function() {
        console.log("getting cell list");
        things = cellItems.find({owner: Meteor.userId(), FileId: "someId"});
        console.log(things);
        return things;
    }
});

<template name="cellular">
    <div id='cellPane'>
        <div id='data'>
            {{#each getCells}}
                <div id="{{_id}}" >
                    <div class='celldesc' contenteditable="true" display="block">
                            {{description}}
                    </div>
                    <div class='cellval' contenteditable="true" display="block">
                            {{vals}}
                    </div>
                    <div class='cellformula' contenteditable="true" display="block">
                            {{formula}}
                    </div>
                </div>
            {{/each}}
        </div>
    </div>
</template>

When I insert the following, it does not seem to fire the helper showing the console statement but I see flicker of the template being updated and then removed. What is happening? How can i correct it?

{owner: Meteor.userId(), FileId: "someId", description: "something", vals: "0", formula: "something else"}

您正在添加具有FileId: "someId"的文档，但是您的助手正在dynaFileId: "someId"上执行find() ，因此，您刚插入的文档不包括在光标中。
