Butterknife onclick does not trigger the method in a fragment

I have the following

public class InventoryFragment extends Fragment {
    @BindView(R.id.fab_fragment_inventory)FloatingActionButton mFab;
private Unbinder unbinder;

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        //return super.onCreateView(inflater, container, savedInstanceState);
        View view = inflater.inflate(R.layout.fragment_inventory, container, false);

        unbinder = ButterKnife.bind(this, view);

return view
}

@OnClick(R.id.fab_fragment_inventory)
    public void newItemDialog(){
        // do stuff
    }

And when I put the method on the xml, it throws this error

<android.support.design.widget.FloatingActionButton
        android:id="@+id/fab_fragment_inventory"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        android:elevation="4dp"
android:onClick="newItemDialog"
        android:src="@drawable/vector_plus"
        app:layout_anchorGravity="bottom|right|end"/>



> java.lang.IllegalStateException: Could not find a method
> newItemDialog(View) in the activity class
> simpleinventory.simpleinventory.activities.InventoryActivity for
> onClick handler on view class
> android.support.design.widget.FloatingActionButton with id
> 'fab_fragment_inventory'

Here's my gradle

dependencies {
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:design:23.2.1'
    compile 'com.android.support:recyclerview-v7:23.2.1'
    compile 'com.android.support:cardview-v7:23.0.0'

    compile 'com.jakewharton:butterknife:8.1.0'
}

EDIT Failed to mention that I did not put on the onclick at first. Without it nothing happens.

You are using onClick with the ButterKnife, it must not be in the xml file. So just remove the android:onClick="newItemDialog" from the xml.

EDIT

You need to add this in the first line of your build.gradle.

apply plugin: 'android-apt'

And in you project build.gradle you need to add the dependency:

buildscript {
   repositories {
      mavenCentral()
   }

   dependencies {
      classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
   }}

You can see it in the github project.
