Callback onUpOrCancelMotionEvent not being called (ObservableScrollView)

I have faced with one problem while implementing ScrollView in my application. I am using great library Android-ObservableScrollView.
My goal is to hide toolbar when user slides down the view and than bring it back when user scrolls up.
I have extended ToolbarControlBaseActivity but the implementation of this abstract class is pretty the same as in the example.
There is callback for handling scrolling and canceling events.

@Override
        public void onUpOrCancelMotionEvent(ScrollState scrollState) {
      //TODO: this method is not being called
        Log.e("DEBUG", "onUpOrCancelMotionEvent: " + scrollState);
        if (scrollState == ScrollState.UP) {
            if (toolbarIsShown()) {
                Log.d("SCROLL", "Hide toolbar");
                hideToolbar();
                scrollUpEvent();
            }
        } else if (scrollState == ScrollState.DOWN) {
            if (toolbarIsHidden()) {
                Log.d("SCROLL", "Show toolbar");
                showToolbar();
                scrollDownEvent();
            }
        }
    }

This callback is never called.
Internally it is implemented in the following way

    if (mCallbacks != null) {
        switch (ev.getActionMasked()) {
            case MotionEvent.ACTION_UP:
            case MotionEvent.ACTION_CANCEL:
                mIntercepted = false;
                mDragging = false;
                mCallbacks.onUpOrCancelMotionEvent(mScrollState);
                break;

Of course I set listener

mScrollable.setScrollViewCallbacks(this);

But it doesn't work.
My layout file has the next content

        </LinearLayout>

    </com.github.ksoichiro.android.observablescrollview.ObservableScrollView>
    <include layout="@layout/toolbar"/>
</FrameLayout>

I haven't debug library internally yet, maybe someone already has the same problem or knows what can cause such behavior.
As temporary solution I am using another callback.

@Override
    public void onScrollChanged(int yPosition, boolean firstScroll, boolean b1) {
        if((yPosition<=mToolBarSize) && (yPosition!= mPreviousYPos)) {
            this.mBannerSlider.startAutoScroll();
            Log.d("SCROLL", "Scrolled up, enable autoslide");
            if(!super.toolbarIsShown()) {
                super.showToolbar();
            }
        }
        else if(firstScroll && yPosition>mToolBarSize) {
            Log.d("SCROLL", "First scroll down disable autoslide");
            this.mBannerSlider.stopAutoScroll();
            if(super.toolbarIsShown()) {
                super.hideToolbar();
            }
        }
        mPreviousYPos = yPosition;
    }

But it seems to work a bit laggy when ToolBar appears
