AngularJS Example:

HTML

<link rel="stylesheet" href="http://twitter.github.com/bootstrap/assets/css/bootstrap.css">
<div ng-app>
    <div ng-controller="ReasonCtrl">
        <table>
            <tr ng-repeat="row in rows">
                <td>
                    <select ng-model="Reason" ng-options="Reason for Reason in ReasonsChoice_normal"></select>
                    <select ng-model="Reason" ng-options="Reason for Reason in ReasonsChoice_ajax"></select>
                </td>
            </tr>
        </table>
    </div>
</div>

JavaScript

function ReasonCtrl($scope, $http, $timeout, $element) { 
    //shouldn't normally use $element, but illustrates the solution

    $scope.rows = [1, 2, 3];
    $scope.Reason = "Apple";
    $scope.ReasonsChoice_normal = ["Apple", "Banana", "Carrot"];


    $http({
        method: 'POST',
        url: '/echo/json/',
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded'
        },
        transformRequest: function (obj) {
            return "json=%5B%22Apple%22%2C%22Banana%22%2C%22Carrot%22%5D"
        }
    }).success(function (data) {
        $scope.ReasonsChoice_ajax = data;
        $timeout(function() {
            $element.find("select").css("width", $element.find("select").css("width"));
        }, 0);
    });
