iTextSharp generate pdf, data is not picked up from - asp.net-mvc

Question

I am requesting data from Azure SQL to be grouped by item and description,then count the quantity.
It is showing correctly on the website with check boxes, but when generate PDF button is pressed it is showing me full list, instead individual items.
This is where I got just to show me group list. I have tried with individual checkbox items, but it is coming back with blank PDF. So, somewhere in code I need to add code where generate pdf understand the group items, instead of individual IDs.
This is my index view and controller:
#model IEnumerable<InventorBOMDelete.Models.InventorBOM1>
<table class="table">
<thead>
<tr>
<th>
#Html.DisplayNameFor(model => model.JOB)
</th>
<th>
#Html.DisplayNameFor(model => model.Description)
</th>
<th>
#Html.DisplayNameFor(model => model.Qty)
</th>
<th>
#Html.DisplayNameFor(model => model.StockNumber)
</th>
<th>
#Html.DisplayNameFor(model => model.Date)
</th>
<th></th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.JOB)
</td>
<td>
#Html.DisplayFor(modelItem => item.Description)
</td>
<td>
#Html.DisplayFor(modelItem => item.Qty)
</td>
<td>
#Html.DisplayFor(modelItem => item.StockNumber)
</td>
<td>
#Html.DisplayFor(modelItem => item.Date)
</td>
<td>
<input type="checkbox" name="selectedIds" value="#item.ID" />
</td>
</tr>
}
</tbody>
</table>
<button type="button" class="btn btn-primary" id="generatePdfBtn">GeneratePDF</button>
#section Scripts {
<script>
$(document).ready(function () {
$('#generatePdfBtn').click(function () {
var selectedIds = [];
$('input[name="selectedIds"]:checked').each(function () {
selectedIds.push($(this).val());
});
if (selectedIds.length === 0) {
alert('Please select at least one item to generate the PDF.');
return;
}
// window.location.href = "/InventorBOM1/GeneratePdf?selectedIds=" + selectedIds.join(',');
window.location.href = "/Customer/GeneratePdf?selectedIds=" + selectedIds.join(', ');
});
});
</script>
