[jQuery] Problem unbinding event from button (function binds event each time it is run)

[window.close]

Hello,

i have a problem with a function (functionB) i bind to the click event
of a button. Every time the function (functionA) which binds this
event is called, it adds functionB another time. So after i called
functionA five times, functionB runs five times on button click. I
tried to unbind this event in functionB, but it does not seem to work.

I hope anybody understands this squirrel dropping of a post ...

An example code with my problem:

        this.functionA = function(parameter1, parameter2){
                $.blockUI(TextEditLayer, {border:'none'});

                $('#button').bind('click', function() {
                        var oAjaxObject = new Array();
                        oAjaxObject[0] = TextEditTextbox.value;
                        oAjaxObject[1] = iJobNumber;
                        myNamespace.myClass.myAjaxMethod(oAjaxObject);
                        $.unblockUI();
                        $('#button').unbind();
                });
        }
