jquery click doesn't work on ajax generated content

Should be done this way.

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

If you have a container that doesn't change during the ajax request, this is more performant:

$('.container').on('click', '.button', function (){
        alert('click!');
    });

Always bind the delegate event to the closest static element that will contain the dynamic elements.

Ok i solved my problem by using the .on() function correctly since i was missing one parameter.

instead of

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

i used

$(".container").on("click", ".button", function() { } );
