Unable to POST data to another controller then STORE in Laravel

I am using Laravel 5.2 and trying to submit a form on dropdown selection. Even though i can do it. But it always redirect to store function which is registered as a resource route.

My routes.php file have routes define like this:

Route::group(['middleware' => ['web']], function () {

    Route::group(['middleware' => 'auth'], function () {

        Route::get('dashboard', function () {
            return view('dashboard.dashboard');
        });

        Route::get('getcurrency', 'QuoteController@getCurrency'); <!--------This is where i have problem--------->
        Route::resource('quotes','QuoteController');
    });

});

I tried naming route as well. But it always take me towards the store function

here is how my dropdown looks like:

<form method="post" action={{ action('QuoteController@getCurrency') }}>
                                <div class="form-group">
                                    <label class="control-label col-md-1">Name</label>
                                    <div class="col-md-5">      
                                        <select class="form-control select2me selectCurrency" name="user_id" onchange="this.form.submit()">
                                            @foreach($users as $user)
                                                <option value="{{$user->id}}">{{ $user->name }} 
                                                    @if(!empty($user->companyname))
                                                        ({{$user->companyname }})
                                                    @else
                                                        ({{$user->email}})
                                                    @endif
                                                </option> 
                                            @endforeach 
                                        </select>

                                    </div>
                                </div>
</form>

I am not able to understand why its always force send the value to store function only, when i have even try to mentioned route, method, url and action. Non of the system working for me.

Is laravel have predefined tendency to take SUBMIT BUTTON to a specific function only?

Here is what my URL is when i have my form :

http://localhost/laravel/public/quotes

Does anyone know why this happens? And how can i fix it?

Thank you!
