Dealing with Typing Errors in Angular with Typescript: Error message 'x' is not a function

I'm facing an issue in my schedule.component.html where I am trying to create a button and link its click event with a function defined in the associated schedule.component.ts file.

The button is coded like this:

<button type="submit"
                (click)="onSubmitExporter2()">
                Propose passes
 </button>

Although the button appears correctly, clicking it doesn't trigger any action and the console displays an error message stating: TypeError: onSubmitExporter2() is not a function.

This is the method I have created:

public onSubmitExporter2(): void {
        console.log('onSubmitExporter2() called');
     const exporter: Exporter = {
    loading: false,
    success: false,
    successMessage: '',
    error: false,
    errorMessage: '',
    info: '',
    exportTime: '',
    exportStatus: '',
    name: 'Download Proba-3 Pass Plan',
    endpoint: '',
    description: '',
    returnFile: false,
    parameters: []
  };
    const exporterPath = 'adapter/gsms/exporter/proba3_pass_plan_export'; // Specify the exporter path
    const queryParams = new Map<string, string>(); // Optional: Add query parameters if needed
    queryParams.set('download', 'true');

 

    this.opsWebDataService.exporter(exporterPath, queryParams).subscribe(
      (r) => {
       if (!exporter.returnFile) {
            exporter.info = r.info;
            exporter.exportTime = r.last_export;
            exporter.exportStatus = r.status;
          } else {
            const disposition = r.headers.get('content-disposition');
            let filename = disposition.split(';')[1].trim().split('=')[1];
            filename = filename.replace(/"/g, '');

 

            const file = new File([r.body], filename,
               { type: r.headers.get('content-type') });
            saveAs(file);
          }

 

          this.onSuccessExport(exporter);
},
      (error) => {
        // Handle errors
        console.error(error);
      }
    );
  }

This code snippet resides within the export class DataTransfer.

If anyone has any solutions, please share them. Thank you!

Problem solved! I managed to fix the issue by moving this method from the data-transfer class to the schedule class in my .ts file. Surprisingly, it only started working correctly after making this change. Grateful for your assistance!
