Ajax request rails checkbox jquery UJS

So I have an app with projects and tasks,where task belongs_to project.I'm trying to change a boolean value of task is_active by clicking on a checkbox in my view.So I've made the checkbox:

<input type="checkbox" name="task" id="task" value="1" data-url="/tasks/"#{task.id} data-remote="true" data-method="post" class="task-check">

I've made a simple toggle action in my tasks controller:

  def toggle
    @task.toggle(:is_active)
  end

But when I'm clicking on a checkbox - I can see only the following error

jquery.self-660adc5….js?body=1:10246 
POST http://localhost:3000/tasks/ 404 (Not Found)send 
@ jquery.self-660adc5….js?body=1:10246ajax

@ jquery.self-660adc5….js?body=1:5227elemData.handle 
@ jquery.self-660adc5….js?body=1:4879

I think params of the checkbox in my view are wrong, but can you please help me to find out what is wrong?

Here is my tasks_controller.rb

class TasksController < ApplicationController
  before_action :set_project
  before_action :set_task, only: [:show, :edit, :update, :destroy, :toggle]
  before_action :authenticate_user!


  def index
    @tasks = @project.tasks
  end

  def show
    #makes use of set_task
  end

  def new
    @task = @project.tasks.new
  end


  def edit
  end

  def references
    respond_to do |format|
      if @task.valid?
        format.html { redirect_to root_url }
        format.json { render :show, status: :created, location: @task }
      else
        format.html { render :home_url }
        format.json { render json: @task.errors, status: :unprocessable_entity }
      end
    end
  end

  def toggle
    @task.toggle(:is_active)
  end

  def create
    @task = @project.tasks.create(task_params)
    respond_to do |format|
      if @task.valid?
        format.html { redirect_to root_url }
        format.json { render :show, status: :created, location: @task }
      else
        format.html { render :home_url }
        format.json { render json: @task.errors, status: :unprocessable_entity }
      end
    end
  end


  def update
    @task = @project.tasks.update(task_params)
    respond_to do |format|
      if @task.update(task_params)
        format.html { redirect_to root_url }
        format.json { render :home_url, status: :ok, location: @task }
      else
        format.html { render :root_url }
        format.json { render json: @task.errors, status: :unprocessable_entity }
      end
    end
  end


  def destroy
    @task.destroy
    respond_to do |format|
      format.html { redirect_to root_url }
      format.json { head :no_content }
    end
  end

  private

  def set_project
    @project = current_user.projects.find(params[:project_id])
  end

  def set_task
    @task = @project.tasks.find(params[:id])
  end

  def task_params
    params.require(:task).permit(:deadline, :body, :project_id)
  end
end

And my view - projects/index.html.erb
