Your problem may be happening because you are assigning the same handler to the click event multiple times. I suggest you check that the line where you assign the handler is not being called multiple times inadvertently. Another solution could be a call to unbind
(deprecated 3.0) or off
(superseeded) first:
$("#myButton").unbind("click").click(myHandler); // deprecated
$("#myButton").off("click").click(myHandler); // superseeded
But without seeing some code I’m just guessing.
