I want to create an event that fires on a change, so I can create something like a <select> tag, but my code is not working with a <datalist>.

This is my HTML:

<input type="text" name="team" id="favorite_team" list="team_list">
<datalist id="team_list">
  <option>Detroit Lions</option>
  <option>Detroit Pistons</option>
  <option>Detroit Red Wings</option>
  <option>Detroit Tigers</option>
</datalist>

And this is my JQuery code:

$('#favorite_team').on('change', function(){    
      alert($(this).val());
});

Your selector is wrong, change the id of your input to favorite or try this code:

$('#favorite_team').on('input', function(){    
      alert($(this).val());
});

You can add the loop to judge the option which is in the list.

$('#favorite_team').on('input', function(){
    var options = $('datalist')[0].options;
    for (var i=0;i<options.length;i++){
       if (options[i].value == $(this).val()) 
         {alert($(this).val());break;}
    }
});
