How to submit value from form, MVC, C#, linq, SQL

Hi A bit help with MVC, thank you

How to submit values from Form with Enumerable<project.model.classA> into a class B ? 
I displayed values from Entity A with groupby (Name) command 
I changed the DisplayFor control for a EditFor control to set values and it will allow the system to submit them. //that's what I think.

class CallRecord 
- I got his values by uploading a file and inserting those values into each matched column on this class
+-------+------+--------------+
|Id     | Name | Cost         |
+-------+------+--------------+
|   1   | Anna |   30.3       |
+-------+------+--------------+
|   2   | Anna |   500        |
+-------+------+--------------+
|   3   | Sam  |   30.3       |
+-------+------+--------------+
|   4   | Tom  |   20.5       |
+-------+------+--------------+
|   5   | Tom  |   20.5       |
+-------+------+--------------+
|   6   | Anna |   20.5       |
+-------+------+--------------+


Grouped result values for class CallRecord: Grupdby Name

Name  Cost
Anna  550.8  
Sam    30.3
Tom    41

but I added a selectList for each displayed grouped result

Name  Cost      Place
Anna  550.8  select place = Place is a list added to each displayed value
Sam    30.3  select place = Place is a list added to each displayed value
Tom    41    select place = Place is a list added to each displayed value

after user select Place value for each displayed on list user is allow to save

save = if sumbit it pass all values to class RegisterCall

class Place

 Id
Name

class RegisterCall

Id
Fname
Place


Desire result after submited from Index 
with a @model IEnumerable<project.Model.CallRecord> to the entity class RegisterCall

class RegisterCall
+-------+------+--------------+
|Id     |Fname |    Place     |
+-------+------+--------------+
|   1   | Anna |   London     |
+-------+------+--------------+
|   2   | Sam  |   Paris      |
+-------+------+--------------+
|   5   | Tom  |   20.5       |
+-------+------+--------------+
