FormCollection inputs on action method have null values - asp.net-mvc

Question

I am trying to get values of form inputs on action method.
MVC View
#using (Html.BeginForm("Report", "Home"))
{
<div class="common_input Volunteer_input">
<div class="row">
<div class="col-sm-12">
<label for="firstName">Reporter:</label>
<div class="select_option_one">
<input type="text" id="ReporterCountries" class="ct-select2 ReporterCountriesList" />
</div>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<label for="firstName">Partner:</label>
<div class="select_option_one">
<input type="text" name="PartnersCountries" id="PartnersCountries" class="ct-select2 CountryList" />
</div>
</div>
</div>
<h3>Comparators</h3>
<div class="row">
<div class="col-sm-12">
<label for="firstName">Partner:</label>
<div class="select_option_one">
<input type="text" name="CompareCountryList" id="CompareCountryList" class="ct-select2 CountryList" />
</div>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<label for="firstName">Rank Growth:</label>
<div class="select_option_one">
<input type="text" name="RankGrowth" id="RankGrowth" class="ct-select2 RankGrowth" />
</div>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<div class="sub_submit">
<button type="submit" class="common_btn hvr-sweep-to-bottom">View<i class="fa fa-long-arrow-right"></i></button>
</div>
</div>
</div>
</div>
}
Action Method for Home Controller
public ActionResult Report(FormCollection form)
{
ViewData["ReporterCountries"] = Request.Form["ReporterCountries"];;
return RedirectToAction("Index","data");
}
When I try to retrieve the values of input on action controller I am receving all the control on the view but values are coming as null.
