asp.net mvc - MVC4 Pass custom view Model back to Controller Action -

-

i have custom class 

public class bloggerviewmodel {             public person blogger;     public list<bloggerwebsite> bloggerwebsites; }

that pass view 

[httpget]     public actionresult edit(int id)     {         blogger = getbyid(id);                     var websites = getbloggerswebsites(id);                     var bloggerviewmodel = new bloggerviewmodel();         bloggerviewmodel.blogger = blogger;         bloggerviewmodel.bloggerwebsites = websites;         return view(bloggerviewmodel);     }

then when post edit action

[httppost] public actionresult edit(bloggerviewmodel entity) {     return view(entity); }

entity null.

my view ( took out allot of code didn't need see. such of text box bindings)

@model bloginect.model.models.bloggerviewmodel  <h2>edit</h2>  @using (html.beginform()) { @html.validationsummary(true)  <fieldset>     <legend>person</legend>      @html.hiddenfor(model => model.blogger.id)      <div class="editor-label">         @html.labelfor(model => model.blogger.firstname)     </div>     <div class="editor-field">         @html.editorfor(model => model.blogger.firstname)         @html.validationmessagefor(model => model.blogger.firstname)     </div>      <div class="editor-label">         @html.labelfor(model => model.blogger.lastname)     </div>     <div class="editor-field">         @html.editorfor(model => model.blogger.lastname)         @html.validationmessagefor(model => model.blogger.lastname)     </div>          <div class="editor-field">              @if (model.bloggerwebsites[0].website != null)             {                 html.editorfor(model => model.bloggerwebsites[0].website);             }             else             {                 @html.textbox("website1")             }          </div>          <div class="editor-field">             @if (model.bloggerwebsites[1].website != null)             {                 html.editorfor(model => model.bloggerwebsites[0].website);             }             else             {                 @html.textbox("website2")             }         </div>          <div class="editor-field">             @if (model.bloggerwebsites[2].website != null)             {                 html.editorfor(model => model.bloggerwebsites[0].website);             }             else             {                 @html.textbox("website3")             }                   </div>      <p>         <input type="submit" value="save" />     </p> </fieldset> }  <div>     @html.actionlink("back list", "index") </div>
