Dynamically populate values for use with jQuery DataTables & Column Filter

I am using jQuery DataTables and the Column Filter plugin.

One of the options in the column filter plugin is to display a dropdown to filter a column's data on.

$("#logTable").dataTable({
    "aaSorting": [[ 1, "desc" ]],
    "bJQueryUI": true,
    "iDisplayLength": 50,
    "aLengthMenu": [10, 25, 50, 100],
    "sPaginationType": "full_numbers",
    "aoColumns": [ 
        { "bSortable": true },
        { "bSortable": true },
        { "bSortable": true },
    ]
}).columnFilter({
    sPlaceHolder: "head:after",
    aoColumns: [ 
        { type: "select", values: ['admin', 'input'] },   /*This creates the dropdown) */
        { type: "text" },
        { type: "text" },
    ]
});

I'm trying to have that list updated dynamically from the page the data table is on.

I've created a hidden element and gave it the value of the possible options

<input type="hidden" id="dValues" value="admin,input">

Then changed my script to

var dValues = $("#dValues").(val);    
$("#logTable").dataTable({
    "aaSorting": [[ 1, "desc" ]],
    "bJQueryUI": true,
    "iDisplayLength": 50,
    "aLengthMenu": [10, 25, 50, 100],
    "sPaginationType": "full_numbers",
    "aoColumns": [ 
        { "bSortable": true },
        { "bSortable": true },
        { "bSortable": true },
    ]
}).columnFilter({
    sPlaceHolder: "head:after",
    aoColumns: [ 
        { type: "select", values: [dValues] },   /*No luck */
        { type: "text" },
        { type: "text" },
    ]
});

I've also tried

<input type="hidden" id="dValues" value="admin,input">

with no luck. If I remove the [] from { type: "select", values: [dValues] } I get each letter of the contents of dValues as an option so I think it's possible to get what I want I just can't figure out how to get each item in properly.
