asp.net mvc - post back the checkbox value in MVC -

i have model below

public class security     {       public long id { get; set; }     public long user_id { get; set; }     public long submenu_id { get; set; }     public long module_id { get; set; }     public long flag { get; set; }     public string module { get; set; }     public string submenu { get; set; }   } 

in flag 1 if user has access menu else 0

i able show in view using pagedlist

@foreach (var item in model) { <tr class=""> <td> @if (item.flag == 1) { <input type="checkbox" name="flags[]" checked="checked" id="@item.id" value="1" /> } else { <input type="checkbox" name="flags[]"  id="@item.id" value="0" />  } </td> <td>@html.displayfor(modelitem => item.module) </td> <td> @html.displayfor(modelitem => item.submenu)</td> </tr> } 

it give below output

here user has access 5 menus , no access 1 admin can change privileges checking , un-checking checkboxes.

my post actionresult signature below

 public actionresult security(client_module_security c1,string[] flags)         {          } 

but not posting values here , flag string contain checked numbers. screen shot below
