Pass javascript function as data-* attribute and execute

One way is to use eval()

jQuery(".container").on("click", "button.marker", function (e) {
    var callback = jQuery(e.currentTarget).data("callback");

    var x = eval(callback)
    if (typeof x == 'function') {
        x()
    }
});

Demo: Fiddle

Note: Make sure it is safe in your environment, ie there is no possibility of script injection because of bad input from users

I think a better idea would be to dynamically bind the events and trigger them. If you wanted them to only be known by other code, you could use custom events.

<button type="submit" class="marker marker1"></button>
<button type="submit" class="marker marker2"></button>
<button type="submit" class="marker marker3"></button>
<button type="submit" class="marker marker4"></button>

<script>
    var $markers = $('.marker');
    $markers.filter('.marker1').bind('customCallback', function(){ alert("hi"); });
    $markers.filter('.marker2').bind('customCallback', function(){ doWork(); });
</script>

Then your other components could invoke them with $(selector).trigger('customCallback');
