Angular JS Pass json data to mvc controller in the form of l

Question

I need to pass json in the form of List to controller in Angular JS Post.

 

I have tried to send data in form of Json to get it as list in the MVC controller. But when I did it , I get only row count at MVC Controller. The variables in the list are null

 

Angular Js Controller

 

$scope.SaveTaxRange = function (){
var formdata = $("#frmTaxSetup").serializeArray();
var uniqueKey = { name: "AngularJS", value: "SaveTaxRange" };
formdata.push(uniqueKey); var tableData = [];
try { $('#tablTaxRange tbody tr').each(function (index, element) {
//tableData = {}; tableData.push({
Min_amt: $(this).find('th:eq(0) input').val(),
Max_amt: $(this).find('th:eq(1) input').val(),
Tax_percent: $(this).find('th:eq(2) input').val(),
Tax_type: $(this).find('th:eq(3) input').val(),
});
tableData.push({
Min_amt: $(this).find('th:eq(0) input').val(),
Max_amt: $(this).find('th:eq(1) input').val(),
Tax_percent: $(this).find('th:eq(2) input').val(),
Tax_type: $(this).find('th:eq(3) input').val(),
});
});
}catch (e) { alert(e); }
uniqueKey = { name: "lstTaxRangeSave", value: tableData };
formdata.push(uniqueKey); var data = {};
$(formdata).each(function (index, obj) {
data[obj.name] = obj.value;
});
$http({
url: "/PayModule/Pay_mas_taxsetup",
method: "Post",
data: { "model": data }
})
.then(function(response){});
};
MVC Model

public class TaxSetupMaster
{
public class TaxRange
{
public string Min_amt;
public string Max_amt;
public string Tax_percent;
public string Tax_type;
public string add;
}
public List<TaxRange> lstTaxRangeSave { get; set; }
}
MVC Controller

[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
public ActionResult Pay_mas_taxsetup( TaxSetupMaster model)
{
var a = model.lstTaxRangeSave ;//Here it shows rowcount 2 but the variables are null. Is it feasible to get the data from html?
}

Thanks in advance
