dropdown/app freezes upon selection

[barron9]

Hi

I am using this simple code, but dropdown freezes itself after i tap an option

<ModalDropdown options={['option 1', 'option 2']}
ref={ (ref) => this.lookaheadFilter = ref }
onSelect={ (idx, value) =>alert(idx) }
/>

if i use alert function or custom function it doesnt matter it stuck

This can be resolved by binding the calling function

can you explain it within a code

[wmfarooqi05]

This line was causing problem

onSelect={(idx, value) => this.onOptionSelect(idx, value)}

After binding it started working

onSelect={(idx, value) => this.onOptionSelect.bind(idx, value)}
