Finally did it after spending hours!

I will post the complete method here for everyone's help.

One needs to use fnServerParams option, which allows adding custom parameters to be sent in the XMLHttpRequest sent to the server. For example:

Here is the coffescript I used:

jQuery ->
  table = $('#logs').dataTable
    bProcessing: true
    bServerSide: true
    sAjaxSource: $('#logs').data('source')
    fnServerParams: (aoData) ->
      applicationName = $("#applicationName").val()
      aoData.push
        name: "applicationName"
        value: applicationName

      return

  $("#applicationName").on "change", ->
    table.fnDraw()
    return

My HTML file contains the input element with id applicationName. Note the fnDraw() element I used to enable redraw request whenever input value changes.
