why I can't use click go to frame and stop in HTML5 Canvas , is there any limit in using it ?

Hello I'm new in Adobe Animate 
I wanna create an interactive multimedia using Adobe Animate with HTML5 Canvas,  I use several buttons and labels on other buttons, I don't experience any problems, why can't the code go to Frame and stop be run in this section? I feel that I have used the labels correctly.

here the SS from previous label, I wanna goto next frame, I want to go to the next frame after that label

this.bt_back.addEventListener("click", fl_ClickToGoToAndStopAtFrame_33.bind(this));

function fl_ClickToGoToAndStopAtFrame_33()
{
this.gotoAndStop("LB_ProsedurBekam");
}

this.bt_home.addEventListener("click", fl_ClickToGoToAndStopAtFrame_34.bind(this));

function fl_ClickToGoToAndStopAtFrame_34()
{
this.gotoAndStop("LB_Home");
}

this.bt_nextmateri.addEventListener("click", fl_ClickToGoToAndStopAtFrame_35.bind(this));

function fl_ClickToGoToAndStopAtFrame_35()
{
this.gotoAndStop("LB_Kontraindikasi3");
}

this.bt_backmateri.addEventListener("click", fl_ClickToGoToAndStopAtFrame_41.bind(this));

function fl_ClickToGoToAndStopAtFrame_41()
{
this.gotoAndStop("LB_Kontraindikasi1");
}

Here the script I use 
thank you for helping me
