cant get an id

cant get an id

i create some code in a div of my site by external php script like this:
$.post("myscript.php", function($data){
            if($data.length >0) {
                $('#mydiv').html($data);
}
});


thats not a problem, i can see the code like this:

<input id="myid-1" class="myclass" type="text" value="" name="myid-1"/>
<input id="myid-2" class="myclass" type="text" value="" name="myid-2"/>
<input id="myid-3" class="myclass" type="text" value="" name="myid-3"/>


now i would like to get the id of a clicked element like this:
$(document).ready(function(){

      $(".myclass").click(function() {
          var currentId = $(this).attr('id');
         alert("Selected ID: "+currentId);
      });
      
      
  });


but it doesn't work, what am i do wrong?
