我想在每个textarea标签中输入console.log().键入textarea会触发printStuff()函数：

$scope.printStuff=  function(customize,item){
            console.log(customize[item.index].data);
        };

当我开始输入任何textarea时,我收到此错误：

angular.js:14290 TypeError: Cannot read property 'data' of undefined
    at b.$scope.printStuff (index.html:31)
    at fn (eval at compile (angular.js:15118),<anonymous>:4:299)
    at b.$eval (angular.js:17922)
    at angular.js:25653
    at Object.<anonymous> (angular.js:28429)
    at q (angular.js:325)
    at Object.$$writeModelToScope (angular.js:28427)
    at angular.js:28420
    at g (angular.js:28339)
    at f (angular.js:28322)

我该如何解决这个错误？
