钛合金数据绑定：如何从单击视图中获取当前模型？

我是Titanium Alloy，MVC框架和Backbone.js的新手，所以我在围绕一些概念时遇到了一些麻烦。

以前曾问过类似的问题：

获取钛合金中单击的TableRow的ID？

Appcelerator钛合金：如何在ScrollableView上存储数据以在单击事件中使用

但是，尽管我尝试遵循答案，但是似乎无法使以下代码正常工作。

基本上，在钛合金中进行数据绑定时，如何将当前模型传递给控制器​​？

（也是，这是我的第一个问题，因此，如果有任何可以改进我的查询的地方，请告诉我，谢谢）。

模型

exports.definition = {
config: {
    columns: {
        "issueNo": "number",
        "date": "string",
        "summary": "string",
        "cover": "string"
    },
    adapter: {
        type: "sql",
        collection_name: "issue"
    }
},
extendModel: function(Model) {
    _.extend(Model.prototype, {
        // extended functions and properties go here
    });

    return Model;
},
extendCollection: function(Collection) {
    _.extend(Collection.prototype, {
        // extended functions and properties go here
    });

    return Collection;
}
};

看法

<Alloy>
<Collection src="issue" />
<Window class="container" onClose="cleanup">
    <View id="header">
        <Label id="title">Christian</Label>
    </View>
    <View id="library" class="body" layout="vertical" dataCollection="issue">
        <View id="issuesList" model="{alloy_id}" onClick="alertModel">
            <ImageView id="cover" image="{cover}"></ImageView>
            <Label id="date" text="{date}"></Label>
            <Label id="summary" text="{summary}"></Label>
            <View class="border"></View>
        </View>
    </View>
    <View id="store" class="body" layout="vertical" visible="false" backgroundColor="yellow">

    </View>
    <View id="footer">
        <TabbedBar id="bottomNav" platform="ios" index="0" onClick="viewSelect">
            <Labels>
                <Label>Library</Label>
                <Label>Store</Label>
            </Labels>
        </TabbedBar>
    </View>
</Window>
</Alloy>

控制器

var Newsstand = require("ti.newsstand");
Newsstand.enableDevMode();

var issues = Alloy.Collections.issue;
issues.fetch();

var issue1 = Alloy.createModel("issue", {
    issueNo: 1,
    date: "1/1/2014",
    summary: "Some text.",
    cover: "/issues/cover_1.png"
});

var issue2 = Alloy.createModel("issue", {
    issueNo: 2,
    date: "1/2/2014",
    summary: "Some text.",
    cover: "/issues/cover_2.png"
});

var issue3 = Alloy.createModel("issue", {
    issueNo: 3,
    date: "1/3/2014",
    summary: "Some text.",
    cover: "/issues/cover_3.png"
});

issues.add(issue1);
issues.add(issue2);
issues.add(issue3);


function viewSelect(tabbedBar) {
    var index = tabbedBar.index,
        library = $.library,
        store = $.store,
        bottomNav = $.bottomNav;

    if (index === 0) {
        library.visible = true;
        store.visible = false;
    } else {
        store.visible = true;
        library.visible = false;
    }
}

function alertModel(e){
    var modelId = e.model,
        model = issues.get(modelId),
        issueNumber = model.get("issueNo");

    alert(issueNumber);
}

function cleanup() {
    $.destroy();
}

$.index.open();
