    start: function () {
       this.$el.on('scroll', this._onScroll.bind(this));
       return this._super();
    },

    _onScroll: function () {

Thank you for your answer.. but unfortunately it doesn't work
Only at the moment of the initial loading , the if condition occurs
And it doesn't happen with scroll
