How I can disable a column inside the Quick Edit Grid using a JSLINK linked to my WebPart

I want to disable the Title column from the Quick Edit grid, inside certain web-parts so i did the following steps:-

1- I went to a list view.

2- Edit the page

3- Edit the web part.

4- Under the "Miscellaneous" tab

5- I add a reference to the following JSLink:-

(function () {

      function registerRenderer() {
        var ctxForm = {};
        ctxForm.Templates = ctxForm.Templates || {};;
        ctxForm.Templates.OnPreRender = function(ctx) {
        var statusField = ctx.ListSchema.Field.filter(function(f) {
            return f.Name === 'Title';
        });
        if (statusField.length>0) {
            statusField[0].AllowGridEditing = false;
        }
    }
        ctxForm.Templates = {
            Fields : {
                'LinkTitle': { //------ Change Hyperlink of LinkTitle
                    View : function (ctx) {
                        if(ctx.CurrentItem.SiteAutomaticallyCreated != null && ctx.CurrentItem.SiteAutomaticallyCreated === 'Yes'){
                        var url = String.format('{0}{1}', "/Programmes/", ctx.CurrentItem.ID);
                        return String.format('<a href="{0}" onclick="EditItem2(event, \'{0}\');return false;">{1}</a>', url, ctx.CurrentItem.Title);
                        }
                        else
                        {
                            var url = String.format('{0}{1}', "/Programmes/Lists/Projects/DispForm.aspx?ID=", ctx.CurrentItem.ID);
                        return String.format('<a href="{0}" onclick="EditItem2(event, \'{0}\');return false;">{1}</a>', url, ctx.CurrentItem.Title);
                        }
                    }
                },
            }
        };
        SPClientTemplates.TemplateManager.RegisterTemplateOverrides(ctxForm);
    }
    ExecuteOrDelayUntilScriptLoaded(registerRenderer, 'clienttemplates.js');


})();

But Title field will still be editable inside the quick edit grid, while the other part of my JS link (ctxForm.Templates) is working well. so can anyone adivce how i can disable the Title field on certain web parts using JSlink ?? as seems this part inside my JSLink is not working well:-

ctxForm.Templates.OnPreRender = function(ctx) {
        var statusField = ctx.ListSchema.Field.filter(function(f) {
            return f.Name === 'Title';
        });
        if (statusField.length>0) {
            statusField[0].AllowGridEditing = false;
        }
    }

Thanks
