javascript - Onclick event is not working in new added rows

This was my code. When I click the add row it will add the row below. but the on click event is working in the first row alone.

It was not working in the rest of the rows.

For dynamically added row, add click event handle using .on() because by the time you attach a click handler for the add row button dynamica rows were not there and hence you need attach click event handler using document which will delegate the event to matched selector.

$(document).ready(function(){
      var i=1;
     $(document).on("click", "#add_row", function(){
        var datepic = "#date" + i;
        $('#addr'+i).html("<td>"+ (i+1) +"</td><td><input id = 'date"+
          i+"'  name='name" + i + 
          "' type='text' placeholder='Name' class='form-control input-md'/>" 
          + "</td><td><input  name='mail" + 
          i + "' type='text' placeholder='Mail'  class='form-control input-md'>"
          +"</td><td><select class='input category'><option selected>d</option></select>"
          +"</td>");

        $(datepic).datepicker();

         $('#tab_logic').append('<tr id="addr'+(i+1)+'"></tr>');
            i++; 
     });

     $(document).on("click","#delete_row", function(){
         if(i>1){
         $("#addr"+(i-1)).html('');
         i--;
         }
     });

    $(document).on("click", ".category", function(){
        alert('df');
     });
});

Change this:

$(".category").click(function(){
    alert('df');
     });

to this:

$(document).on('click', '.category', function(){
        alert('df');
});

Its is called delegated events.
