Clear Text Box based on Click of button

I am using Textbox to display current selections from Listbox based on user input.

When I click on value in Listbox it get selected and data gets filtered and Texbox gets updated with what value is selected.

I also have a button called "Clear Selection" which removes filters on DataSource. (DS-1.ClearAllFilters();) which does remove filters applied by Listbox to data in Dashboard.

Now - How can I clear the values displayed in the Textbox at the same time?

Is there a script available to clear values in Textbox?

Thanks,

Rajan
