web page enmbeded vbcs page, want to reload vbcs page when user enter value in company field

Summary:

Hi Experts

I have a page created in VBCS which accepts the supplier name in the URL unless it is passed it won't route the flow in VBCS to actual page i.e. supplier management and i have embedded same in the supplier registration page as shown below. As the value of company is enter after the page loads I want the web page component what i embedded in fusion to load as soon as users enters the value in company field.

Here i have embedded the page in supplier registration page but at beginning company name will be empty but when user enters the company name it should reload the web page i.e. my vbcs page or retrigger the page to load as my page needs supplier name / company name for routing the flow.
