类的静态成员从不同的上下文调用产生不同的值

代码如下：
export class EventDispatcher {
public static cnt = 0;
public static _DISPATCHERS_DIC = {};

public static dispatchEvent(module, event) {
    if (module) {
        this.getInstance(module).dispatchEvent(event);
    } else {
        for (var k in EventDispatcher._DISPATCHERS_DIC) {
            EventDispatcher._DISPATCHERS_DIC[k].dispatchEvent(event);
        }
    }
}

public static getInstance(module) {
    cc.log(`event>> [${module}] inst(${EventDispatcher.cnt}) get >>>`);

    let tm = EventDispatcher._DISPATCHERS_DIC[module];
    if (!tm) {
        //////////  testing.
        let icnt = 0;
        for (let kv in EventDispatcher._DISPATCHERS_DIC) {
            let estr = (EventDispatcher._DISPATCHERS_DIC[
                kv
            ] as EventDispatcher).toString();
            cc.log(
                `event>> handle(${icnt++}): ${kv} dispatcher: ${estr}] `
            );
        }
        //////////
        tm = new EventListenerHandle(module);
        EventDispatcher._DISPATCHERS_DIC[module] = tm;
        EventDispatcher.cnt++;
    }
    cc.log(
        `event>> [${module}] inst(${EventDispatcher.cnt}) get: ${tm.uuid}`
    );
    return tm;
}

}

另写一个类：
class XXComponent extends cc.Componen {
onLoad() {
EventListenerHandle.getInstance(“aaa”);
// 这里会得到一个值， EventDispatcher._DISPATCHERS_DIC 中增加一个值， 总数 1
}

onStart() {
EventListenerHandle.getInstance(“aaa”);
// 这里会得另一个值， EventDispatcher._DISPATCHERS_DIC 中增加一个值， 总数依然为 1
}
}

已经卡了3天了， 跪求各位大神救命
