why I see validation messages before form submiting - razor

Question

I've created a form and when I load the page with it I see validation messages before I submit the form. Why? You can download my code from github
The similar question. It's because of mvc4
#model MyMustAgreeValidation.Models.NewUserProfileModel
#using (Html.BeginForm())
{
#Html.ValidationSummary(true)
<fieldset>
#Html.MyEditFor(m=>m.Login)
#Html.MyEditFor(m=>m.Password)
#Html.MyEditFor(m=>m.ConfirmPassword)
#Html.MyEditFor(m=>m.DisplayName)
#Html.MyEditFor(m=>m.Email)
#Html.MyEditFor(m=>m.Homepage)
#Html.MyEditFor(m=>m.AgreementAccepted)
<p><input type="submit" value="#CreateRes.CreateProfileButton"/></p>
</fieldset>
}
Where Html.MyEditFor is
public static MvcHtmlString MyEditFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression)
{
return html.Partial("Item", new LabelEditorValidation() { Label = html.LabelFor(expression), Editor = html.EditorFor(expression), Validation = html.ValidationMessageFor(expression) });
}
And Item is partial view:
#model MyMustAgreeValidation.Models.LabelEditorValidation
<div class="editor-label">
#Model.Label
</div>
<div class="editor-field">
#Model.Editor
#Model.Validation
</div>
LabelEditorValidation:
public class LabelEditorValidation
{
public MvcHtmlString Label { get; set; }
public MvcHtmlString Editor { get; set; }
public MvcHtmlString Validation { get; set; }
}

EqualAttribute.js:
jQuery.validator.addMethod("equal", function (value, element, param) {
if($(element).attr("type")=="checkbox")
{
value = String($(element).attr("checked"));
param = param.toLowerCase();
}
return (value == param);
});
jQuery.validator.unobtrusive.adapters.addSingleVal("equal", "valuetocompare");
