MvvmCross List - Click on item and button in item

I try to have a list that do different action with a button in the line item, and tap on the item list.

Here is the list

<Mvx.MvxListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/RecapResponsesListView"
    local:MvxBind="ItemsSource ReponsesRecapList; ItemClick GoToLandscapeQuestion;"
    local:MvxItemTemplate="@layout/item_response" />

Here is the item response :

[...]
<Button
    android:id="@+id/ResponseValidate"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="20"
    android:layout_gravity="center"
    android:gravity="center"
    android:text="Valider"
    local:MvxBind="Click ConfirmResponseCommand; Enabled ConfirmButtonEnabled" />
</LinearLayout>

My button works fine, I can tap on it without any problem, but since I added it, the ItemClick no longer works. I can remove my button from the item, and the ItemClick works again, so it's not the implementation of this tap that doesn't. I think adding a button block the item click...

Do you have any ideas on why, and how to fix this ??

Thanks !
