youtube xml transcript file is not valid
===

I tried this code to load a youtube video transcript file

    var rqst=$.ajax( {
        dataType : 'jsonp', 
        type : 'GET', 
        url : 'https://www.youtube.com/api/timedtext?v=bwOhfoewMYs&lang=en&callback=alert', 
        
       success : function(response) {
    alert("SUCCESS");
                 }, 
       error : function() {
           alert("failed."); }
       }
    );

and this error appears

    Uncaught SyntaxError: Unexpected token < 

and the variable `rqst` not assigned, so I can't access the file's RespondText 
screenShot:<br>
