My guess is that the buttons you created are not yet on the page by the time you bind the button. Either bind each button in the $.getJSON function, or use a dynamic binding method like:

$('body').on('click', 'button', function() {
    ...
});

Note you probably don't want to do this on the 'body' tag, but instead wrap the buttons in another div or something and call on on it.

You could also create the input button in this way   var button     lt input type  button  id  questionButton  value   variable   gt   lt br   gt       It might be the syntax of the Button creation that is off somehow

the simple and easy way to do that is use on event      body   on  click    element  function          somthing       but we can say this is not the best way to do this  I suggest a another way to do this is use clone   method instead of using dynamic html  Write some html in you file for example    lt div id  div1  gt  lt  div gt    Now in the script tag make  a clone of this div then all the properties of this div would follow with new element too  For Example   var dynamicDiv   jQuery   div1   clone true     Now use the element dynamicDiv wherever you want to add it or change its properties as you like  Now all jQuery functions will work with this element

You create buttons dynamically because of that you need to call them with  live   method if you use jquery 1 7  but this method is deprecated  you can see the list of all deprecated method here  in newer version  if you want to use jquery 1 10 or above you need to call your buttons in this way     document  on  click    selector   function             Your Code       For Example  If your html is something like this   lt div id  btn-list  gt       lt div class  btn12  gt MyButton lt  div gt   lt  div gt    You can write your jquery like this    document  on  click     btn-list  btn12   function             Your Code
