When rendering partial view from view jQuery script is not working. When adding the same dynamically it works

I'm adding some functionality to an old project (ASP.NET MVC 5)

In view I render existing items:

    @if (Model.ItemsVM != null)
    {
        for (int i = 0; i < Model.ItemsVM.Count(); i++)
        {
            Model.ItemsVM[i].Index = i; Html.RenderPartial("_AddItem", Model.ItemsVM[i]);
        }
    }

and later via AJAX I call the same partial view from controller to add additional items.

The pickle is that the jQuery code from that partial view is performing as expected if added dynamically, but not if rendered normally by Html.RenderPartial.

Additional info:

jQuery JavaScript Library v3.1.1 is loaded at the bottom

    var [email protected] = parseFloat($("#ItemsVM_@(Model.Index)__Popust").val() != '' ? $("#ItemsVM_@(Model.Index)__Popust").val() : 0);
    if ([email protected] > 0) {
        $('#ItemsVM_@(Model.Index)__Sum').val(Math.round(([email protected] * [email protected]) - ((([email protected] * [email protected]) * [email protected]) / 100)).toFixed(2));
    }
    else {
        $('#ItemsVM_@(Model.Index)__Sum').val(Math.round([email protected] * [email protected]).toFixed(2));
    }
    SumSums();
});
</script>

I know that the problem is with jQuery being loaded before something, but all variations with document / ready etc. doesn't work and breaks the script when loaded dynamically.
