ASP.Net MVC: Keep decimal value when sending from View to Controller

I am working with .Net 6 and Mvc. I have a problem with decimals, when bound from the view to the controller, it considers them integers. For example, from the view I send 25.6 to the controller it arrives 256.0

 This my code.

<button type="button" id="btnConfirm">Confirm</button>

<input id="txtName" name="txtName" disabled="disabled">
<input id="txtAmount" name="txtAmount" disabled="disabled">

$('#btnConfirm').on('click', confirmTransaction['confirm']);

var confirmTransaction = {
    'confirm': function (e) {
        var data = {
            Name: $('#txtName').val(),
            Amount:  $('#txtAmount').val()                      
        }
        SendTransaction(data);
    }
}

function SendTransaction(transaction) {
    return $.ajax({
    url: '@Url.Action("InsertTransaction", "TransactionController")',
    method: 'POST',
    beforeSend: ShowLoading('Please wait.'),
    complete: function (d) {
            HideLoading();
        },
    success: function (data) {
            console.log(data);
            if (data.resultado !== 'OK') {
                alertify.alert("Error!");
                return;
            }
        toastr.success('Success.');
            return;
        },
    error: function (data) {
        alertify.alert('Error.');
            HideLoading();
        },
    data: { transaction }
    });
}

/*At this point, the decimals arrive as integers.*/
public JsonResult InsertTransaction(Transaction transaction)                                             
{
    /*More code*/
}

public class Transaction {
    public string Name {get; set;}
    [DisplayFormat(AppyFormatInEditMode=true, DataFormatString = "{0:C}")]
    public decimal Amount {get; set;}
}

Thanks.
