When clicking the tab very fast two tab's got Selected

When try to click the tabs very fast two tabs got Selected in Jquery SmartWizard.js plug-in i tried this way but no luck any one experienced this... and also tried .on /.off events no luck.

$($this.steps).bind("click", function (e) {

    //e.stopImmediatePropagation();       
    $($this.steps).unbind("click");

    if ($this.steps.index(this) == $this.curStepIdx) {

        return false;
    }
    var nextStepIdx = $this.steps.index(this);
    var isDone = $this.steps.eq(nextStepIdx).attr("isDone") - 0;
    if (isDone == 1) {
        _loadContent($this, nextStepIdx);
    }

    $($this.steps).bind("click");
    return false;
});

hi guy's thank you for your efforts i solved the issue by blocking the UI using UI block plugin

$($this.steps).on("click", function (e) {

    e.preventDefault();
    e.stopImmediatePropagation();
    if ($(this).attr('class') !== 'disabled' && $(this).attr('class') !== 'selected' && $(this).attr('class') !== 'error') {

        $('div.swMain').block({ message: "Processing..." });
    }

    try {

        if ($this.steps.index(this) == $this.curStepIdx) {

            $('div.swMain').unblock();
            return false;
        }

        var nextStepIdx = $this.steps.index(this);
        var isDone = $this.steps.eq(nextStepIdx).attr("isDone") - 0;
        if (isDone == 1) {           
            e.preventDefault();
            _loadContent($this, nextStepIdx);

        }
    }
    catch (e) {

        $($this.steps).on("click");
        console.log("Fast click Error ===>   " + e);
    }


    if ($(this).attr('class') !== 'disabled' && $(this).attr('class') !== 'selected' && $(this).attr('class') !== 'error') {

        $('div.swMain').unblock();
    }

    return false;
});
