使用renderjs在视图层创建了一个摇杆，摇杆addEventListener监听滑动，在监听函数里面，使用this.$ownerInstance.callMethod函数不起作用

使用renderjs在视图层创建了一个摇杆，摇杆addEventListener监听滑动，在监听函数里面，使用this.$ownerInstance.callMethod函数不起作用，请问我该怎样才能调用逻辑层函数？
代码如下：

   renderBtn() {  
            var bottom = document.getElementById(".bottom");  
            if (!bottom) {  
                bottom = document.createElement("div");  
                bottom.classList = ["bottom"];  
                document.body.appendChild(bottom);  
                var that = this;  
                window.off = function() {  
                    plus.nativeUI.confirm("确定结束吗？", (e) => {  
                        if (e.index == 0) {  

                        }  
                    });  
                };  
                bottom.innerHTML = [  
                    "<div class='btn'><div class='back'></div></div>",  
                    "<div class='ybtn off' onclick='off()'></div>",  

                ].join('');  
            }  
            var zbtn = document.querySelector(".btn");  
            console.log('zbtn:', zbtn);  
            zbtn.addEventListener('touchstart', function(e) {  

                console.log('点击左摇杆');  
                this.startX = e.touches[0].clientX;  
                this.startY = e.touches[0].clientY;  

            })  
            zbtn.addEventListener('touchmove', function(e) {  
                this.endX = e.touches[0].clientX;  
                this.endY = e.touches[0].clientY;  
                var that = this;  
                console.log('that======:' + that);  
                //获取滑动距离  
                var distanceX = this.endX - this.startX;  
                var distanceY = this.endY - this.startY;  

                //判断滑动方向  
                if (Math.abs(distanceX) > Math.abs(distanceY) && distanceX > 0) {  
                    console.log('往右滑动:' + distanceX);  
                    that.callMethod("doOver");  
                } else if (Math.abs(distanceX) > Math.abs(distanceY) && distanceX < 0) {  
                    console.log('往左滑动:' + distanceX);  
                } else if (Math.abs(distanceX) < Math.abs(distanceY) && distanceY < 0) {  
                    console.log('往上滑动');  
                } else if (Math.abs(distanceX) < Math.abs(distanceY) && distanceY > 0) {  
                    console.log('往下滑动');  
                }  

            })  
            zbtn.addEventListener('touchend', function() {  

                console.log('Swipe direction: ' + direction);  
                // console.log('松开左摇杆');  
                this.startX = 0;  
                this.startY = 0;  
                this.endX = 0;  
                this.endY = 0;  

                var back = document.querySelector(".back");  
                back.style.left = 40 + 'px';  
                back.style.top = 40 + 'px';  

            })  

        },
