Answer 1

Anytime, you use dynamically created tags, you must use

$(document).on('#event','#selector',function () {...});

so here

$(document).on('click','.sleep_avail',function () {...});

Because event handlers bind to the currently elements, they have to exist on the page when .on() is called

Here is the working DEMO http://jsfiddle.net/ARBdU/

$(document).on('click','.btnn, .sleep_avail',function () {  
 if($(this).hasClass('btnn'))
 {
    ...   
 }
 else if($(this).hasClass('sleep_avail'))
 {      
   ...
 }
});

$(document).on('click','.sleep_avail',function () {
