Try this.

var crtRdo=new Ext.form.Radio({
            xtype:"radio",
            name:"mtype",
            inputValue:"radiovalue"
          });
crtRdo.disable();

Try to add this Standard override.

Ext.override(Ext.form.Radio, {
    onClick : function(){
    	if(this.el.dom.checked != this.checked){
    	    var els = this.el.up('form').select('input[name='+this.el.dom.name+']');
    	    els.each(function(el){
    	        if(el.dom.id == this.id){
    	            this.setValue(true);
    	        }else{
    	            Ext.getCmp(el.dom.id).setValue(false);
    	        }
    	    }, this);
        }
    }
});

ExtJS 6.5

Ext.define('Overrides.form.field.Radio', {
  override: 'Ext.form.field.Radio',

  initComponent: function (radio) {
    radio.dom.onclick = function(){
      radio.setValue(!radio.value );
    }
  }
});
