javascript - jquery plugin "jStepper" - not working for me -

i trying use plugin: http://jstepper.emkay.dk/default.aspx increments values nicely, when try launch "onstep" event, runs right after page loads, not when value incremented. hope can point me in right direction, maybe similar plugin exists? or maybe simple fix in plugin's source. can try in "demo" box: $(".txttesting").jstepper({onstep:alert("test")});

you have this.....

$(obj).jstepper({onstep:testfunction});  function testfunction(objtextfield, bdirection, blimitreached) { alert("test"); } 

or

 $(obj).jstepper({       onstep: function(objtextfield, bdirection, blimitreached) {                    alert("test");       } }); 

thanks
