onstatechange event . this no longer works any ideas?

[unitedworx]

on previous slider I was using (SalesSeek/jslider) there was an ostatechange event that got fired every time the slider changed, this no longer works any ideas?

here is my code

slider works fine but onstatechange function never gets called

$( document ).ready(function() {

	$( 'input[data-slider="jslider"]' ).each(function( ) {
		
	    var from =  $(this).data('sliderFrom');
	    var to =  $(this).data('sliderTo');
	    var heterogeneity =  $(this).data('sliderHeterogeneity');
	    var step =  $(this).data('sliderStep');
	    var dimension =  $(this).data('sliderDimension');
		var input_field = $(this);		
	
		$(this).slider({
			  from: from,
			  to: to,
			  heterogeneity: eval(heterogeneity),
			  limits: false,
			  step: step,
			  dimension: ' '+dimension,
			  onstatechange: function( value ){
				
				alert('tell form it was changed');
			  	
			  	if (input_field.val()==from+';'+to){
					input_field.val('');
				}
				
				input_field.closest("form").change();
			  }  
		});
		
	});

});
