Need to get the values of the checked checkboxes in Webgrid

As the title says. I am having trouble on accessing the checkbox on webgrid.

My Webgrid

<div id="grid" >
        @grid.Table(
        tableStyle: "table table-responsive table-bordered",
            columns: grid.Columns(
                grid.Column(format:@<text> <input type="checkbox" value="Check_@item.SubjectCode" name="ids" /></text>, header: "Check"),
                grid.Column(columnName: "SubjectCode", header: "SubjectCode"),
                grid.Column(columnName: "SubjectName", header: "SubjectName"),
                grid.Column(columnName: "SubjectDescription", header: "SubjectDescription"),
                grid.Column(columnName: "Units", header: "Units"),
                grid.Column(columnName: "Schedule", header: "Schedule"),
                grid.Column(columnName: "Instructor", header: "Instructor"),
                grid.Column(columnName: "Room", header: "Room")
            )

        )
        <div class="row">
            <div class="col-md-6">
                @grid.PagerList(mode: WebGridPagerModes.All, paginationStyle: "pagination pagination-small pagination-right")
            </div>
        </div>

        @Html.Hidden("dir", grid.SortDirection)
        @Html.Hidden("col", grid.SortColumn)

        <div class="col-md-1">
            <a class="btn btn-success btn-block" id="subjectSave" >Save</a>
        </div>
        <div class="col-md-1">
            <a class="btn btn-success btn-block" href="~/Account/Home">Back</a>
        </div>

    </div> 
</div>

My Jquery

<script>
    $('#subjectSave').click(function mySave(e) {
        var arrItem = [];
        var commaSeparatedIds = "";
        $("#grid  input[type=checkbox]").each(function (index, val){
            debugger
        })

    })
</script>

I'm having trouble on what to put in

$("#grid input[type=checkbox]").each(function (index, val){

I only saw a code for "li" and none for webgrid. I need to get all the values of the checked checkbox put it in array and send it to the controller so I can queried each of it.

I hope someone can help me. Im still studying java so I'm not yet familiar of other kind of things. Thank you in advance
