How do i strongly bind an Ienumerable class to a view in MVC asp.net?

Please i have a model class below

 public class EditJob
 {
        public JobPost JobPost { get; set; }
        public IEnumerable<JobRequirement> JobRequirement { get; set; }
        public IEnumerable<JobResponsibility> JobResponsibility { get; set; }
  }

I strongly bind the class to a view and want to use it for editing in controller. I have a controller which receives model like below.

[HttpPost]
public ViewResult SaveJob(EditJob model)
{

}

I Dynamically bind my Ienumerable to texboxes in my view like below.

@for (int i = 0; i < Model.JobResponsibility.Count();i++ )
 {

  JobWebsite.Domain.Enitities.JobResponsibility rs = Model.JobResponsibility.ElementAt(i);
  <label class="control-label">Responsibility :</label>
   Html.Hidden("Responsibility[" + i + "]", rs);
   @Html.TextBoxFor(x => rs, new { @class = "form-control" }) <br />

 }

On my button click, I realized the two IEnumerable methods from my model are not binding . The JobPosts in the model is not empty, yet my Ienumerable properties not always empty . I added a hidden field holding my values but i am having problem passing them to the controller. Please how do i achieve this ?

If you inspect you html, you will see that the controls name attributes do not have the correct indexers for binding. Either change the collections to IList and use as follows: (note you have not posted the model for JobResponsibility so I'm assuming it contains properties ID and Name)

@for (int i = 0; i < Model.JobResponsibility.Count; i++ )
{
  @Html.HiddenFor(m => m.JobResponsibility[i].ID)
  @Html.TextBoxFor(m => m.JobResponsibility[i].Name)
}

Alternatively, create a custom EditorTemplate for type of JobResponsibility

/Views/Shared/EditorTemplates/JobResponsibility.cshtml

@model JobResponsibility
@Html.HiddenFor(m => m.ID)
@Html.TextBoxFor(m => m.Name)

and in the main view

@model EditJob
@using(Html.BeginForm())
{
  .....
  @Html.EditorFor(m => m.JobResponsibility)
  ....
}

I can't see anything at the moment binding to JobResponsibility. Try changing

Html.Hidden("Responsibility[" + i + "]", rs);

to

Html.Hidden("JobResponsibility[" + i + "]", rs);
