send File and Data in Ajax

I'm trying to send file and data together to Controller when I send File it work correctly but When I try to send data and file nothing I get.

                contentType: false,
                processData: false,

and as I remove this codes I can send data what should I do?

                 <div class="form-group ">
                  <input class="form-control" id="title" name="title" type="text"/>

                 </div>
                 <div class="form-group ">
                  <textarea class="form-control" cols="40" id="desc" name="textarea" rows="10"></textarea>
                 </div>
                 <div class="form-group ">

                  <div class="">
                   <div class="radio">
                    <label class="radio">
                     <input name="answer"  id="respawn" type="radio" value="1"/>
                     1
                    </label>
                   </div>
                   <div class="radio">
                    <label class="radio">
                     <input name="answer" type="radio" value="2"/>
                     2
                    </label>
                   </div>
                   <div class="radio">
