I have a button click in javacript file through which i am making a ajax call.

strange is that, when i am running application through localhost, it working fine. But when i publish it, then try to run, this button event fired variable number of times, sometimes twice sometime thrice.But mostly twice. In button event i am giving a alert as validation. Moreover,this button click event come in document.ready function.

The code snippet is:

$("#btnUpdate").click(function () {
    if ($("#drpstatusEdit option:selected").text() == 'Closed') {
        var OffshoreResourceIds = '';
        $('#drpOffshoreUsersEdit :selected').each(function (i, selected) {
            OffshoreResourceIds = OffshoreResourceIds + ',' + $(selected).val();
        });

        if ($("#txtTicketDesc").val() == '')
            alert('description cannot be blank');
        else searchUserWithoutCriterion();
    }
    else {
        updateTickets();

    }
    getTicketCount();
});

function updateTickets() {
    //some code with alert
    alert("something");
}

How to make this to get fired only once as it working fine when running through localhost.(i dont want button to unbind).
