app.ts

```javascript
...,
entryComponents: [
    CfDemoDynamicComponentLoaderExampleOne,
    CfDemoDynamicComponentLoaderExampleTwo,
    CfButtonComponent,
    CfWeatherComponent
]

...

selectedComponent: any;

button = new ButtonModel ({
      label: "My CfButtonComponent",
      color: {
          foreground: "black",
          background: "primary"
      },
      iconProperty: null,
      iconPosition:"right"
  });
weather = new WeatherComponentModel ({
      defaultCity: "Paris"
});  

selectComponent(componentName) {
    switch (componentName) {
      case 1:
        this.selectedComponent = {
          component: CfDemoDynamicComponentLoaderExampleOne,
          inputs: {
            inputText: 'This is example one.'
          }
        };
        break;
      case 2:
        this.selectedComponent = {
          component: CfDemoDynamicComponentLoaderExampleTwo,
          inputs: {
            onClick: () => {
              alert('This is example two.');
            }
          }
        };
        break;
      case 3:
          this.selectedComponent = {
            component: CfButtonComponent,
            inputs: {
              settings: this.button
            }
          };
          break;
      case 4:
          this.selectedComponent = {
            component: CfWeatherComponent,
            inputs: {
              settings: this.weather
