Question is too long for title so I pasted it below

Within the link function of myDirective, write a function that uses the ngModelCtrl to send all new values typed into the <input> to the console.log function.

Hi Andrew,

Try logging the value of the contents variable.

      ngModelCtrl.$render=function() {
        var contents = ngModelCtrl.$viewValue;
        console.log(contents);

Hope this helps!
