Ninject for winforms - how to apply ninject DI for MDI child form in C# windows form app

I am developing desktop base application using c# windows form. Recently I added NInject to my project, it is working good but when i call to child forms from MDI form it's asking constructor parameter of child form because i am using form constructor to pass interface parameter. i don't know how to resolve it. 
please can any one help me to resolve it. this is my sample project

**CompositionRoot**

    public class CompositionRoot
    {
        private static IKernel _ninjectKernel;

        public static void Wire(INinjectModule module)
        {
            _ninjectKernel = new StandardKernel(module);
        }

        public static T Resolve<T>()
        {
            return _ninjectKernel.Get<T>();
        }
    }

**ApplicationModule**

    public class ApplicationModule : NinjectModule
    {
        public override void Load()
        {
            Bind(typeof(IRepository<>)).To(typeof(GenericRepository<>));
            Bind(typeof(ITest)).To(typeof(TestImpl));
        }
    }

**Program**

    static class Program
    {
        
        [STAThread]
        static void Main()
        {
            CompositionRoot.Wire(new ApplicationModule());
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            //Application.Run(new Form1());
            Application.Run(CompositionRoot.Resolve<Form1>());

        }
    }

**MDI Form**

    public partial class Form1 : Form
    {
        
        private IRepository<Process> _processRepository;

        public Form1(IRepository<Process> productionRepository, ITest test)
        {
            this._processRepository = productionRepository;
            this._test = test;
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            
            Form2 frm = new *Form2()*;
            frm.Show();
        }
    }

**Child form**

    public partial class Form2 : Form
    {
       
        private ITest _test;

        public Form2(ITest test)
        {
            _test = test;
            InitializeComponent();
        }
        
        private void button1_Click(object sender, EventArgs e)
        {
            var a = _test.DisplayRow();
            MessageBox.Show(a);
        }
    }

**ITest**

    public interface ITest
    {
        string DisplayRow();
    }


**TestImpl**

    public class TestImpl : ITest
    {
        public string DisplayRow()
        {
            return "Test service";
        }
    }


**GenericRepository**

    public class GenericRepository<T> : IRepository<T>
    {
        public override string ToString()
        {
            return "MyRepository with type : " + typeof(T).Name;
        }
    }


**IRepository**

    public interface IRepository<T>
    {
    }
