asp.net mvc 4 - MVC 4 - pass parameter to controller on button click -

i have mvc 4 project has save button when clicked asks user confirm , submits whole form controller model input, not formcollection. need add button form called submit. how can pass parameter differentiate between save , submit? i'd continue using jquery function confirmation. here code snippets:

javascript  function saveplan() {     if (validateamounts() != true) {     var message = "do want save? ";     createconfirmationmessage(message, '$("#form_fiscalyearplanning").submit();');     return; }  } 

jquery

function createconfirmationmessage(message, confirmactiontotake, cancelactiontotake) {      $('#project_confirmationquestion').html(message);              if (confirmactiontotake !== null) {         $('#button_confirmationaccept').attr('onclick', confirmactiontotake);     }             else {         $('#button_confirmationaccept').removeattr('onclick');     }              if (cancelactiontotake !== null) {         $('#button_confirmationcancel').attr('onclick', cancelactiontotake);     }             else {         $('#button_confirmationcancel').removeattr('onclick');     }     $('#modal_confirmation').modal('show'); }/ 

view

@using (html.beginform("fiscalyearplanning", "teammanagement", formmethod.post, new { id = "form_fiscalyearplanning" })) 

:::

<button class="btn btn-primary project_formbuttonpopover" id="button_saveplan" name="button_saveplan" onclick="saveplan();" data-toggle="popover" data-content="save plan, not submit review.">save</button> 

controller

public actionresult fiscalyearplanning(vm_fiscalyearplanning model) 

the input buttons have value. can detect value of input button @ controller.

<input type="submit" value="submitbutton"> <input type="submit" value="savebutton">
