play from currentFrame and stop on targeted frames in animate CC (html5)

Question

I was struggling with this code and still not find correct way of doing this. so posted here.

All frame are in my nested movieclip (mc_1). now I want to go on target frame by clicking on the button inside movieclip from the currentFrame as shown in below image.
here is my code:

this.stop();

var a = this;

a.mc_1.t.addEventListener("click",test_1)
function test_1(){
if(a.mc_1.currentFrame > 0){
var tds = 29 +(a.mc_1.currentFrame-a.mc_1.currentFrame); //wanted to get targeted frame number
a.stage_freezeobject.gotoAndStop(tds); \\ this will directily jump onto frame29 but I wanted to play from current frame and stop on 29.
}

any help will much appreciate.

below are 2 examples of two different currentFrames and play direction whereas 1 direction is normal play and 2nd direction is reverse play. it will be good if both ways are possible, if not, then 1 of this will fullfill my need.

when currentFrame > target frame, you need to start a loop (eg, ticker) to play backwards and if < play forwards. eg

// assuming target is defined
function test_1(){
if(a.mc_1.currentFrame > target && !createjs.Ticker.hasEventListener("tick")){ 
createjs.Ticker.addEventListener("tick", reversePlayF);
} else if(a.mc_1.currentFrame < target && !createjs.Ticker.hasEventListener("tick")){ 
a.mc_1.play();
createjs.Ticker.addEventListener("tick", playF);
}
}
function reversePlayF() { a.mc_1.gotoAndStop(a.mc_1.currentFrame-1);
if(a.mc_1.currentFrame==target){
createjs.Ticker.removeEventListener("tick", reversePlayF);
}

function playF{
if(a.mc_1.currentFrame == target){
a.mc_1.stop();
createjs.Ticker.removeEventListener("tick", playF);
} }
