C# WebAPI - Calling POST Method Within Controller with Model as Parameter

I can't figure out why the below calls to my "GetBatch" webapi method isn't working. I am not sure if I need to specify the route, etc. I do have other HttpPost methods but note that I am specifically trying to call the method I defined below.

What can I do to fix? The URL should be correct because different actions do get called. Thank you for your time.

JavaScript:

var accountGetBatchURL = '@HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority)@Url.Content("~/")api/Account/GetBatch';
	function () {
		'use strict';
		var lastColumns = oTable.context[0].aoColumns;
		var lastSearch = oTable.context[0].aoPreSearchCols;
		var suppliedSearchParameters = new Array();
		for (var i = 0; i < lastSearch.length; ++i) {
			if (lastSearch[i].sSearch !== "") {
				suppliedSearchParameters.push({ "column": lastColumns[i].mData, "value": lastSearch[i].sSearch });
			}
		}
		var dataToSend = { 'searchParameters': suppliedSearchParameters };$.ajax({
			url: accountGetBatchURL,
			type: 'POST',
			cache: false,
			contentType: 'application/json',
			dataType: 'json',
			data: JSON.stringify(dataToSend),
			error: function (jqXHR, textStatus, errorThrown) {
				bootbox.alert("There was a problem with sending the search parameters to the service for processing. Extended information: Error Number: " + textStatus + " Error Thrown: " + errorThrown);
			},
			success: function (json) {
				bootbox.alert("Successfully sent search parameters to LMS Search service!")
			}
		});
	}

C# Model Code:

public class AccountSearchDTO
	{
		public AccountSearchParameterDTO[] searchParameters { get; set; }
	}

	public class AccountSearchParameterDTO
	{
		public string column { get; set; }
		public string value { get; set; }
	}

	public class AccountSearchResultsDTO
	{
		public int numOfRows { get; set; }
	}

C# Account Controller Code:

[HttpPost]
	public AccountSearchResultsDTO GetBatch([FromBody] AccountSearchDTO param)
	{
		AccountSearchResultsDTO results = new AccountSearchResultsDTO();
		results.numOfRows = 0;
		return results;
	}
