Add this to your main timeline;

//will stop 'play', 'gotoAndPlay' and 'rewind', 'gotoAndRewind' functions
MovieClip.prototype.stopAll = function () {
        delete this.onEnterFrame;
        this.stop();
}

//will stop 'rewind', 'gotoAndRewind' functions
MovieClip.prototype.stopRewind = function () {
        delete this.onEnterFrame;
}

//will play the timeline backwards and continal to loop until 'stopAll', 'stopRewind' or 'pause' are called
//note: the 'rewind' function will cancel the 'play' function BUT the 'play' function will not cancel the 'rewind' function
//you must call 'stopAll' or 'stopRewind' before using 'play' when your timeline is playing backwards
MovieClip.prototype.rewind = function () {
        this.stop();
        this.onEnterFrame = function () {
                if (this._currentframe > 0) {
                        this.prevFrame ();
                } else {
                        this.gotoAndStop (this._totalframes);
                }
        }
}

//will goto the specified frame and play the timeline backwards and continal to loop until 'stopAll', 'stopRewind' or 'pause' are called
MovieClip.prototype.gotoAndRewind = function (frame) {
        this.gotoAndStop (frame);
        this.rewind();
}

//will pause the timeline for the specified amount of time. will always play forwards when the pause has finished
MovieClip.prototype.pause = function (time) {
        delete this.onEnterFrame;
        secondsToPause = time;
        pauseInt = setInterval (this, "restart", secondsToPause * 1000);
}

restart = function () {
        clearInterval (pauseInt);
        play();
}




And then put this after your onClick function:
instancename.stopAll();
instancename.rewind();

I tried a few ways but could not get your solution to work. After a bit of reaserach I found this (see attached).
The script is dropped into the button works a treat.

var rewind:Boolean = false; 
btn_back.addEventListener(MouseEvent.CLICK, forward); 
btn_back.addEventListener(MouseEvent.CLICK, backwards); 
 
function forward(event:MouseEvent):void{ 
    rewind = false; 
    addEventListener(Event.ENTER_FRAME, eFrame); 
} 
 
function backwards(event:MouseEvent):void{ 
    rewind = true; 
    addEventListener(Event.ENTER_FRAME, eFrame); 
} 
 
function eFrame(e:Event):void{ 
    if(currentFrame <= 1 || currentFrame >= 60){ 
        //  limit movement between frame 1-60 
        removeEventListener(Event.ENTER_FRAME, eFrame); 
    } else { 
        //  move forward or back depending on rewind 
        (rewind) ? prevFrame() : nextFrame(); 
    } 
}
