使用AngularJS的数据表中的单元格按钮

我正在使用angularjs建立网站，并且正在从Web服务获取数据。我需要将该数据填充到数据表中，并为每一行创建一个编辑按钮。经过一番调查，我想出了这个

问题是ng-click无法正常工作，可能是因为我需要编译注入到表格单元格中的html。我已经尝试了几种方法，但是不幸的是，我对角度还是很陌生，而且我似乎不明白我如何做到这一点。我真的需要这个帮助。

这是我的指令：

dialogApp.directive('myTable', function ($compile) {
return {
    restrict: 'E, A, C',
    link: function (scope, element, attrs, controller) {
        var dataTable = element.dataTable(scope.options);

        scope.$watch('options.aaData', handleModelUpdates, true);

        function handleModelUpdates(newData) {
            var data = newData || null;
            if (data) {
                dataTable.fnClearTable();
                dataTable.fnAddData(data);
            }
        }
    },
    scope: {
        options: "="
    }
};}); 

控制器：

dialogApp.controller('DataTableTestController', ['$scope', function($scope){
$scope.coisas = "coisas";
$scope.botaoEdit = function(a){
    console.log(a);
};

$scope.options = {
    "sDom": '<"H"lf>t<"F"ip>',
    "bStateSave": true,
    "bPaginate": false,
    "bLengthChange": false,
    "bFilter": true,
    "bSort": true,
    "bInfo": true,
    "bAutoWidth": false,
    "sPaginationType": "full_numbers",
    aoColumns: [{
        "sTitle": "name"
    }, {
        "sTitle": "price"
    }, {
        "sTitle": "category"
    }, {
        "sTitle": "action"
    }, null],
    "aaSorting": [[ 0, "asc" ]],
    aoColumnDefs: [
        { "bSortable": true, "aTargets": [0] },
        { "bSortable": false, "aTargets": [1,2,3,4] }
    ],
    bJQueryUI: true,
    aaData: []
};

var dbStuff = [
    {
        "name": "Stuff1",
        "price": 10000000.00,
        "description": "Expensive Stuff",
        "wanna":"buy"
    },
    {
        "name": "Stuff2",
        "price": 20000000.00,
        "description": "Oh my...",
        "wanna":"have money"
    }
]

for (var key in dbStuff){
    $scope.options.aaData.push([dbStuff[key].name,
                                dbStuff[key].price,
                                dbStuff[key].description,
                                dbStuff[key].wanna,
                                "<button ng-click=\"botaoEdit("+dbStuff[key].name+")\">test button</button>"
                               ]);
}

$scope.counter = 0; }])

和HTML：

<link type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/themes/redmond/jquery-ui.css" rel="stylesheet" />
<link rel="stylesheet" type="text/css" href="http://ajax.aspnetcdn.com/ajax/jquery.dataTables/1.8.2/css/jquery.dataTables.css">

<div ng-app="tableExample">
    <div ng-controller="DataTableTestController">   
        {{ coisas }}
        <table my-table options="options" class="jquery-datatables"></table>
    </div>
</div>
