I don't get why my code doesn't work.

var students = [ 
  { 
   name: 'Dave',
    track: 'Front End Development',
    achievements: 158,
    points: 14730
  },
  {
    name: 'Jody',
    track: 'iOS Development with Swift',
    achievements: '175',
    points: '16375'
  },
  {
    name: 'Jordan',
    track: 'PHP Development',
    achievements: '55',
    points: '2025'
  },
  {
    name: 'John',
    track: 'Learn WordPress',
    achievements: '40',
    points: '1950'
  },
  {
    name: 'Trish',
    track: 'Rails Development',
    achievements: '5',
    points: '350'
  }
];

var message = '';
var student;

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;
}


while (true) {
  student_name = prompt("please search the student's name")
  for (var i = 0; i < students.length; i += 1) {
  student = students[i];
    if ( students.name.indexOf(student_name) > -1 ) {
      message += '<h2>Student: ' + student.name + '</h2>';
      message += '<p>Track: ' + student.track + '</p>';
      message += '<p>Points: ' + student.points + '</p>';
      message += '<p>Achievements: ' + student.achievements + '</p>';
    } else {
      student_name = prompt("please search the student's name")
    }
  }
}
