Error validating form with dynamically added rows in laravel

I am trying to dynamically add new row to a form using JQuery. This works well but my form validation does not work. Please I need help here. Note: I am working with laravel 5.3

This is my html file

<form action="" method="post">
            @if(isset($errors))
                @if(count($errors) > 0)
                    <div class="alert alert-danger">
                        <ul>
                            @foreach($errors->all() as $error)
                                <li> here</li>
                                @endForeach
                        </ul>
                    </div>
                    @endIf
                    @endIf

                    <div class="row" id="newlink">
                    <div class="form-group col-sm-12">
                        <div class="form-group col-sm-2">
                            <label class="">Title</label>
                            <input name="title[]" id="title" type="text" class="form-control"/>
                        </div>
                        <div class="form-group col-sm-3">
                            <label class="">Description</label>
                            <textarea name="description[]" class="form-control"></textarea>
                        </div>
                        <div class="form-group col-sm-2">
                            <label class="">Unit Price</label>

                        <div class="form-group col-sm-2">

                        </div>
                        <div class="form-group col-sm-3">

                        </div>
                    </div>
                    </div>
                    <div id='newlinktpl' style='display:none'>
                        <div class="form-group col-sm-12">

                                <textarea name="description[]" class="form-control"></textarea>
                            </div>
                            <div class="form-group col-sm-2">
                                <label class="">Unit Price</label>
                                <input name="price[]" id="price" type="text" class="form-control"/>

                                <input name="quantity[]" id="quantity" type="text" class="form-control"/>
                            </div>
                            <div class="form-group col-sm-3">
                                <label class="">Total</label>
                                <input name="total[]" id="total" type="text" class="form-control"/>
                            </div>
                            <div class="form-group col-sm-3">
                                <input name="request_id[]" id="request_id" type="hidden" class="form-control" value="@if(isset($detail))   @endif "/>
                            </div>
                        </div>
                    </div>
                    <div class="form-group col-sm-12">
                        <button class ="btn btn-sm btn-danger" onclick="new_link();"><i class="fa fa-plus"> Add Item</i></button>
                    </div>
                    <div class="form-group col-sm-12">
                        <input type="submit" value="Submit" class="btn btn-sm btn-primary"/>
                    </div>
                    </form>

This is my javascript file

var ct = 1;
        function new_link()
        {

            ct++;
            var div1 = document.createElement('div');
            div1.id = ct;
            // link to delete extended form elements
            var delLink = '<div style="text-align:right;margin-right:65px"><a href="javascript:delIt('+ ct +')">Del</a></div>';
            div1.innerHTML = document.getElementById('newlinktpl').innerHTML + delLink;
            document.getElementById('newlink').appendChild(div1);
            //e.preventDefault();
            event.preventDefault();
        }
        // function to delete the newly added set of elements
        function delIt(eleId)
        {
            d = document;
            var ele = d.getElementById(eleId);
            var parentEle = d.getElementById('newlink');
            parentEle.removeChild(ele);
        }

This is my controller file where I am trying to validate the data entered into these rows

public function saveRequests(Request $request){
        $method = $request->isMethod('post');
        if($method){

            $validator = Validator::make($request->all(), [
                'title' => 'required|max:255',
                'description' => 'required|max:255',
                'price' => 'required|numeric',
                'quantity' => 'required|numeric',
                'total' => 'required|numeric'
            ]);
            if($validator->fails()){
                return redirect('/saveRequests')->withErrors($validator)->withInput();
                //echo "failed";
            }


        }  
    }
