Android studio: SearchView doesn't update the new details of item

Question

I'm using RecyclerView and also implemented SearchView with it. While i'm searching for an object, I can find it, I can update it details but after i success to update the data, I still see the old details of the item. only when i close the search i will see the up-to-date object. This is the class with the search functions:

public class ProductCompare extends AppCompatActivity {

Context mContext=this;
private RecyclerView mRecyclerView;
private ImageAdapterProduct mAdapter;
private DatabaseReference mDatabaseRef;
private ValueEventListener mDBListener;
private List<Product> mItem;
FloatingActionButton fab;
private int mDate, mMonth, mYear;
Date date2;
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd",java.util.Locale.getDefault());

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_product_compare);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    fab=findViewById(R.id.fab);

    mRecyclerView=findViewById(R.id.mRecyclerView);
    mRecyclerView.setHasFixedSize(true);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

    mItem=new ArrayList<>();
    mAdapter=new ImageAdapterProduct(ProductCompare.this,mItem);
    mRecyclerView.setAdapter(mAdapter);

    mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
            if(dy > 0){
                fab.hide();
            } else{
                fab.show();
            }
            super.onScrolled(recyclerView, dx, dy);
        }
    });

    mDatabaseRef= FirebaseDatabase.getInstance().getReference("Product");

    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            final DialogPlus dialogPlus=DialogPlus.newDialog(mContext)
                    .setContentHolder(new ViewHolder(R.layout.dialogcontentforfab))
                    .setExpanded(true,1150) // was 1200
                    .create();

What should i need to change / add to let it be up-to-date also in search mode? Thank you.
