在调用通过构造函数引入的函数时，我可以避免在Typescript中使用“this”这个词吗？

I have:

class AdminHomeController {

    private config1; // I tried different variations here but none worked
    public config2;  //

    constructor(
                 private $scope: IAdminHomeControllerScope
               ) {
                     this.config = $scope.config; // << this works
                 }

    static $inject = [
        '$scope'
    ];

    configChanged = (clear) => {
        this.config.clear();
    };

}
class AdminHomeController {

    priv
