How to post and request data to a controller method in Laravel using JQuery and bootstrap multi step forms?

I want to send multi step form data to a controller method when i click the save button and later request that data in the controller method using Jquery. I have tried some steps but even the button doesn't seem to do anything.

I have this route to store treatment data.

Route::post('/patients/{patient}/medications','PatientMedicationsController@store')->name('saveTreatment')->middleware('auth');

Some of the fields are

heartRate, bloodPressure, otherFindings, duration

And id of the submit button is save. i have this Jquery code in my blade view.

<script>
    $(document).ready( function() {
    $('#save').click( function () {
    $.ajax({
        url:("route('saveTreatment')"),
        type: 'POST',
        data: {'submit': true},
        success: function () {
            alert('Treatment has been saved');
           }
         });
       });
   });
</script>

The controller method to store is store.

I want the multi step form data to be received by the controller method and then saved to the database.
