Use    document  on  click     btn a   function      alert   button clicked          to add the listener for the dynamically created button   alert     btn a   val       will give you the value of the button

Question 1  Use  delegate on the div to bind a click handler to the button   Question 2  Use   this  val   or this value  the latter would be faster  inside of the click handler   this will refer to the button       pg menu content   on  click     btn a   function        alert   this  val           div       lt div data-role  fieldcontain   gt         lt input type  button  value  Dynamic Button  id  btn a    gt    appendTo  div clone    appendTo   pg menu content

Use a delegated event handler bound to the container       pg menu content   on  click     btn a   function        console log this value         That is  bind to an element that exists at the moment that the JS runs  I m assuming  pg menu content exists when the page loads   and supply a selector in the second parameter to  on    When a click occurs on  pg menu content element jQuery checks whether it applied to a child of that element which matches the  btn a selector   Either that or bind a standard  non-delegated  click handler after creating the button   Either way  within the click handler this will refer to the button in question  so this value will give you its value

Just create a button element with jQuery  and add the event handler when you create it    var div       lt div   gt      data-role     fieldcontain         btn       lt input   gt                    type     button                 value    Dynamic Button                 id       btn a                 on                         click  function                          alert   this value                                                      div append btn  appendTo      pg menu content   empty        FIDDLE
