no output on the est id value

[Jay Anne Otadora]

I have an ID called est that doesn't show the value that should reflect on hmtl.

everytime i put a zip id the est id should reflect the estimate value. 

here is my html code 

        <div class="row">

            <div class="input-field col s4">

            <i class="material-icons prefix">location_searching</i>

            <input  id="zip" type="text" class="validate">

            <label for="zip">Zip Code</label>

         </div>

        <div class="input-field col s4">

            <i class="material-icons prefix">location_searching</i>

            <input disabled id="est" type="text" class="validate">

            <label for="est" class="active">Estimate </label>

        </div>

      </div>

      </div><!--close row-->

Here is my js code:

var url = "https://docs.google.com/spr1eadsheets/d/1Mllf6M76R5umdazrWotHaEgHLHyJNn_TSgadLyXB5Eo/edit#gid=1324130870";

function getCost(zipCode){

  var ss = SpreadsheetApp.openByUrl(url);

  var ws = ss.getSheetByName("optionV2");

  var data = ws.getRange(1,1,ws.getLastRow(),2).getValues;

//   //searching in the zipcodelist

   var zipCodeList = data.map(function(r){return r[0];});

   var costList = data.map(function(r){return r[1];});

   var position = zipCodeList.indexOf(zipCode);

//   // check if its greater -1

   if(position > -1){

//     //return the item on the same position

          return costList[position];

  }else{

        return 'no Recored';

    }

 

}

 document.getElementById("zip").addEventListener("input", getEstimate);

function getEstimate(){

      var zipCode = document.getElementById("zip").value;

       google.script.run.getCost(zipCode);

     

   

      // if(zipCode.length >= 2){

       google.script.run.withSuccessHandler(updateEstimate).getCost(zipCode);

   

             

      // }

    }

     

    //  //accept whatever the getcost has

     function updateEstimate(cost){

    //show value on estimate label

      document.getElementById("est").value = cost;

       M.updateTextFields();

      }
