Laravel 5.7 Controller check which button has been clicked - laravel-5.7

Question

I am current using laravel 5.7 I have a form in a bootstrap modal that has 2 tabs and each tab will display its submit button respectively. I am trying to capture which submit button has been click from my controller. I have already tried using Input::get('btn-name'); and $request->submit == 'btn-name' but neither of the methods are working for me. I tried dd(Input::all()) but it did not even capture the clicked button
Update
i have tried changing both my button name to create-btn and added these in my controller and it displays "none" in the dd($action);
$action = Input::get('create-btn','none');
if($action == 'create-team'){
$project->type = 'Team';
dd($action);
}else if($action == 'create-personal'){
$project->type = 'personal';
dd($action);
}else{
dd($action);
}
HTML
The <a> tag is not inside the <form> tag is because it is located at the modal's footer hence i use an on-event function
<!--Team Tab Button-->
<button action="{{route('project.store')}}"
method="POST"
class="btn btn-primary"
name="create-btn"
value="create-team"
onclick="event.preventDefault(); document.getElementById('submit-form
personal').submit();">Createdd changes
</button>`
<!--Personal Tab Button-->
<button action="{{route('project.store')}}"
method="POST"
class="btn btn-primary"
name="create-btn"
value="create-personal"
onclick="event.preventDefault(); document.getElementById('submit-form-
personal').submit();">Createdd changes
</button>`
Controller
public function store(Request $request)
{
$this->validate($request, [
'p_name' => 'required|min:6|max:50',
'start_date' => 'required',
'end_date' => 'required',
]);
$project = new Project;
$project->p_name = $request->input('p_name');
$project->start_date = $request->input('start_date');
$project->end_date = $request->input('end_date');
$project->colab = $request->input('colab');
dd(Input::all());
if($request->submit == 'create-team'){
$project->type = 'team ';
$project->save();
}
return 123;
}
