jQuery click event not working after adding class

In my JSP page I added some links:

<a class="applicationdata" href="#" id="1">Organization Data</a>
<a class="applicationdata" href="#" id="2">Business Units</a>
<a class="applicationdata" href="#" id="6">Applications</a>
<a class="applicationdata" href="#" id="15">Data Entity</a>

It has a jQuery function registered for the click event:

$("a.applicationdata").click(function() {
    var appid = $(this).attr("id");
    $('#gentab a').addClass("tabclick");
    $('#gentab a').attr('href', '#datacollector');
});

It will add a class, tabclick to <a> which is inside <li> with id="gentab". It is working fine. Here is my code for the <li>:

<li id="applndata"><a class="tabclick" href="#appdata" target="main">Application Data</a></li>
<li id="gentab"><a href="#datacollector" target="main">General</a></li>

Now I have a jQuery click handler for these links

$("a.tabclick").click(function() {
    var liId = $(this).parent("li").attr("id");
    alert(liId);        
});

For the first link it is working fine. It is alerting the <li> id. But for the second <li>, where the class="tabclick" is been added by first jQuery is not working.

I tried $("a.tabclick").live("click", function(), but then the first link click event was also not working.

Since the class is added dynamically, you need to use event delegation to register the event handler

$(document).on('click', "a.tabclick", function() {
    var liId = $(this).parent("li").attr("id");
    alert(liId);        
});

You should use the following:

$('#gentab').on('click', 'a.tabclick', function(event) {
    event.preventDefault();
    var liId = $(this).closest("li").attr("id");
    alert(liId);  
});

This will attach your event to any anchors within the #gentab element, reducing the scope of having to check the whole document element tree and increasing efficiency.

.live() is deprecated.When you want to use for delegated elements then use .on() wiht the following syntax

$(document).on('click', "a.tabclick", function() {

This syntax will work for delegated events

.on()

Based on @Arun P Johny this is how you do it for an input:

<input type="button" class="btEdit" id="myButton1">

This is how I got it in jQuery:

$(document).on('click', "input.btEdit", function () {
    var id = this.id;
    console.log(id);
});

This will log on the console: myButton1. As @Arun said you need to add the event dinamically, but in my case you don't need to call the parent first.

UPDATE

Though it would be better to say:

$(document).on('click', "input.btEdit", function () {
    var id = $(this).id;
    console.log(id);
});

Since this is JQuery's syntax, even though both will work.

on document ready event there is no a tag with class tabclick. so you have to bind click event dynamically when you are adding tabclick class. please this code:

$("a.applicationdata").click(function() {
    var appid = $(this).attr("id");

   $('#gentab a').addClass("tabclick")
    .click(function() {
          var liId = $(this).parent("li").attr("id");
         alert(liId);        
      });


 $('#gentab a').attr('href', '#datacollector');

});
