dropdown with attribute field names

I am building a search tool which has a text box ,a dropdown and a submit button.
The drop down would essentially contain attribute field names and on submit
i have code as bellow

findParams = new esri.tasks.FindParameters();
            findParams.returnGeometry = true;
            findParams.layerIds = [5];
            findParams.searchFields = dojo.byId("drop_down").value;

            findParams.outSpatialReference = map.spatialReference;
function doFind() {
            //Set the search text to the value in the box 
            findParams.searchText = dojo.byId("Risk_Score").value;
            findTask.execute(findParams, showResults);
        }
        
        function showResults(results) {
            //This function works with an array of FindResult that the task returns 
            map.graphics.clear();
            //var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([98, 194, 204]), 2), new dojo.Color([98, 194, 204, 0.5]));
            var symbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASH, new dojo.Color([0, 0, 0]), 3);

            //create array of attributes 
            var items = dojo.map(results, function (result) {
                var graphic = result.feature;
                graphic.setSymbol(symbol);
                map.graphics.add(graphic);
                return result.feature.attributes;
            });


            //Create data object to be used in store 
            var data = {
                identifier: "OBJECTID",  //This field needs to have unique values 
                label: "OBJECTID", //Name field for display. Not pertinent to a grid but may be used elsewhere. 
                items: items
            };
           
            //Create data store and bind to grid. 
            store = new dojo.data.ItemFileReadStore({ data: data });
            var grid = dijit.byId('grid');
            grid.setStore(store);

            //Zoom back to the initial map extent 
            map.setExtent(startExtent);

        }

does this idea work?? and i have problem in loading field names to the drop down.
Any help on this would be great. Thanks in advance.
