I am using jquery colorbox and jquery date picker. My problem is date picker doesn't work in my popup window using jquery colorbox.

Any help would greatly appreciated.

I am using this plugin http://keith-wood.name/datepick.html

here is my form which containe bidthday

    <div id="add-employee-container">
        <form name="create_employee" id="create_employee" method="post" action="<?php echo site_url('admin/employee/save') ?>">
            <label><span class="text-red">* </span>First Name:</label><input name="firstname" type="text" class="required"/><br /><br />
            <label><span class="text-red">* </span>Middle Name:</label><input name="middlename" type="text" class="required"/><br /><br />    
            <label><span class="text-red">* </span>Last Name:</label><input name="lastname" type="text" class="required"/><br /><br />

     </div>

here is my javascript

$(document).ready(function(){
    $('#date-pick').datepick();             
});

in the above code it works fine but when i used it in jquery colorbox it doesn't work anymore. call jquery colorbox below

$(".add-employee").colorbox({
    width:"50%",
    inline:true, 
    title:' ',
    href:"#add-employee-container",
    onLoad: function(){
        $('#date-pick').datepick();         
    },
    onClosed: function (){
        validator.resetForm();
    },          
});
