createClassObject - TextInput Component

I need to create TextInput Components at runtime. I can create the object just fine but I can not position or size the component. I assume this is due to the properties (x,y,width,height) being READ-ONLY but assumed that createClassObject would at least set the initial values as per the initObject. I am just testing right now and the initObject is {text:"Testing", width:100} I also tried {text:"Testing", width:"100"}.
Is it possible to use the initObject to size the TextInput Component, or does anyone know a work-around?
