Hi Preeti Mahajan,

I think issue in line No 10.

your element "id" is not exists in dom at time.

I think you hide the element using inside if block in widget tree.

try to make use of visible property true/false of element based on the condition.

Not to inject or remove html element using if block in widget tree.
