gr.ClearButton and elem_id is not working

Spaces
1

In my space my gr.ClearButton is not working. I am not understanding, how can I fix it? I have tried different solutions provided here but nothing is working for me. How can I make the gr.ClearButton working like a ‘clear’ button works in gr.Interface? I am also trying to add button styles using CSS. I am using elem_id, it is also not working after adding ID in my CSS file. Can anyone help me please?

Below is my code:

with gr.Blocks(css="styles.css") as demo:
    gr.HTML("<h1>Bangla PoS Taggers</h1>")
    gr.HTML("<p>Translate a sentence from Bangla to English and then tag the PoS of the translated sentence.</p>")

    with gr.Row():
        with gr.Column():
            inputs = [
                gr.Textbox(
                    label="Enter Bangla Sentence", 
                    placeholder="বাংলা বাক্য লিখুন"
                ),
                gr.Dropdown(
                    choices=["Google", "BanglaNMT", "MyMemory"], 
                    label="Select a Translator", 
                    value="Google"
                ),
                gr.Dropdown(

            ]

            btn = gr.Button(value="Submit", elem_id="btn")
            btn_clear = gr.ClearButton(value="Clear")
