Add custom codecompletions to cucumber step

Hi all, i wanna get autocomplete for cucumber step parameters, i try make Completion Contributor, and add results, but when i press Ctrl+Space(caret in the step) i see link to step definition and not see my parameters.

How i can add elements to completion list?

I have elements in project with annotation @Name

public class TestCompletion extends CompletionContributor {
    public TestCompletion() {
        extend(CompletionType.BASIC,
                PlatformPatterns.psiElement(),
                new CompletionProvider<CompletionParameters>() {
                    public void addCompletions(@NotNull CompletionParameters parameters,
                                               ProcessingContext context,
                                               @NotNull CompletionResultSet resultSet) {
                        PsiElement psiElement = parameters.getOriginalPosition();
                        assert psiElement != null;
                        Project project = psiElement.getProject();
                        Collection<PsiAnnotation> psiAnnotations = StubIndexImpl.getInstance().get(JavaStubIndexKeys.ANNOTATIONS, "Name", project, GlobalSearchScope.allScope(project));
                        List<LookupElement> completeElements = new ArrayList<>();
                        for (PsiAnnotation annotation : psiAnnotations) {
                            String current = annotation.getText()
                                    .replace("@Name(\"", "")
                                    .replace("\")", "");
                            if (current.length() > 0){
                                completeElements.add(LookupElementBuilder.create(current));
                            }
                        }
                        resultSet.addAllElements(completeElements);

                    }
                });
    }

}
