Ios应用内采购请求数据功能未启动

我使用的是phonegap 2.6.0 in，ios 7 sdk设备是5.1。我已经实现了应用内采购管理插件

在deviceready函数上，我尝试调用requestData((函数，但它没有启动，因为它应该是

function onDeviceReady(){
    alert(window.plugins.inAppPurchaseManager); //-->This alerts as Object
    window.plugins.inAppPurchaseManager.onPurchased = function(transactionIdentifier, productId, transactionReceipt) {
        updatePurchaseTable(productId);
        window.location.reload();
        console.log('purchased: ' + productId);
    }
    window.plugins.inAppPurchaseManager.onRestored = function(transactionIdentifier, productId, transactionReceipt) {
        console.log('restored: ' + productId);
         /*See the developer guide for details of what to do with this */
    }
    window.plugins.inAppPurchaseManager.onFailed = function(errno, errtext) {
        alert('failed: ' + errtext);
    }
    window.plugins.inAppPurchaseManager.requestProductData("ProductId1", function(result) {
            alert(result.id);  //-->this doesn't happen
            console.log("productId: " + result.id + " title: " + result.title + " description: " + result.description + " price: " + result.price);
                  //window.plugins.inAppPurchaseManager.makePurchase(result.id, 1);
            }, function(id) {
            alert("Invalid product id: " + result.id);
            }
    );

}

我也在本地中发出了警报

InAppPurchaseManager.m

- (void) requestProductData:(CDVInvokedUrlCommand*)command函数中不显示任何警报的文件。
