I have been using this jQuery before I use $.ajax(); and it was working good:
    $(document).ready(function(){
    var urlSerilize = 'some link';
    var appList = $("#applications > li > a");
    var appCheck = $('input[type=checkbox][data-level="subchild"]');
    var installbtn = $('#submitbtn');
    var form = [];
    var checked = [];
    //var appList = $(".body-list > ul > li");
    //var appCheck = $('input[type=checkbox][data-level="subchild"]');
    appList.click(function(){
        console.log('here!');
        if($(this).children().find("input").is(":checked")){
            $(this).children().find("input").prop('checked', false);
            $(this).children('form').removeClass('checked');
            $(this).removeClass("li-checked");
            var rmValue = $(this).children('form').attr('id');
            form = jQuery.grep(form, function(value) {
              return value != rmValue;
            });
        }else{
            $(this).children().find("input").prop('checked',true);
            $(this).addClass("li-checked");
            $(this).children('form').addClass('checked');
            form.push($(this).children('form').attr('id'));
        }
        console.log(form);
    });
    installbtn.on('click', function () {
        event.preventDefault();
        jQuery.each( form, function( i, val ) {
            console.log(val);
            var request = $.ajax({
                    url: urlSerilize,
                    type: 'GET',
                    data: $('#'+val).serialize(),
                    success: function( response ) {
                        console.log( response );
                        $('#applications').html();
                        $('#apps_box').html();
                    }
                });
            request.done(function(msg){
                console.log('Ajax done: ' + 'Yeah it works!!!');
            });
            request.fail(function(jqXHR, textStatus){
                console.log('failed to install this application: ' + textStatus);
            });
        });
    });
});
but after I used this ajax code the .click() jQuery event don't work anymore:
$(document).ready(function() {
    /* loading apps */
    //console.log('active');
    var request = $.ajax({
        url: 'some link',
        type: 'GET',
        dataType: 'html',
        data: {id: 0},
    })
    request.done(function(data) {
        console.log("success");
        $('#applications').empty().append(data);
    })
    request.fail(function() {
        console.log("error");
    })
    request.always(function() {
        console.log("complete");
    });
    //end loading apps
    var showmore = $('.showapps');
    showmore.click(function(){
        var parent = $(this).parent('.tv_apps');
        var displayC = parent.children('.body-list').css('display');
        console.log(displayC);
        if (displayC=='none') {
            parent.children('.body-list').show('400');
            $(this).children().find('img').rotate({animateTo: 180});
        }else{
            parent.children('.body-list').hide('400');
            $(this).children().find('img').rotate({animateTo: 0});
        };
    });
});
at first place I though it was because of the ajax loads and don't stop, then i was wrong.
I have tried the window.load=function(); DOM function to load the script after Ajax finish loading and also was wrong.
So please if there any idea to fix this problem,
Thanks.
This is the event I want it to be fixed:
appList.click(function(){
    console.log('here!');
    if($(this).children().find("input").is(":checked")){
        $(this).children().find("input").prop('checked', false);
        $(this).children('form').removeClass('checked');
        $(this).removeClass("li-checked");
        var rmValue = $(this).children('form').attr('id');
        form = jQuery.grep(form, function(value) {
          return value != rmValue;
        });
    }else{
        $(this).children().find("input").prop('checked',true);
        $(this).addClass("li-checked");
        $(this).children('form').addClass('checked');
        form.push($(this).children('form').attr('id'));
    }
    console.log(form);
});
