is it possible to set the attribute as [config] with value as configForScroll using setAttribute in javascript?

Question

I am working in a angular4 project where I had used ngx-slimscroll which has the tag with attribute as given below

<perfect-scrollbar [config]="configForScroll"></perfect-scrollbar> .

Now, here my requirement is to create <perfect-scrollbar> element dynamically using document.createElement() function which I have done successfully.But, on setting the attribute as [config] I am getting error as

Uncaught DOMException: Failed to execute 'createAttribute' on 'Document': The qualified name provided ('[config]') contains the invalid name-start character '['. So, is there any way to set this kind of attribute as shown in below code

var patt = document.createAttribute("[config]");
patt.value = "configForScroll";

Please find me a way to fix it. Thanks in advance

You cannot create an attribute named '[config]' , with special chars '[' and ']' . Doing so will raise a INVALID_CHARACTER_ERR exception as pointed out here

INVALID_CHARACTER_ERR if the parameter contains invalid characters for XML attribute.

but you can create an attribute named 'config';

document.createAttribute("config");//valid

Please note that dynamically appending component tag won't work as expected. Angular will not detect those change. Your newly appended node will be considered as a plain Dom node, and not as angular component.

If your intention is to add a dynamic component then please look into to dynamic-component-loader and this stackoverflow answer => How can I use/create dynamic template to compile dynamic Component with Angular 2.0?
