Are you using datagrid package?

You can use formatValue to put button into DataTables:

DataTables::create(array(
    "columns"=>array(
        "your-column-name"=>array(
            "formatValue"=>"<button onclick='openModal(@value)'>View</button>"
        )
    )
))

Now you can write your own openModal() function:

function openModal(param)
{
    ...
}
