Dropdown doesn't close when I click outside the dropdown

Hi when I show the dropdown menu and then click outside the region of dropdown it doesn’t close. Why?

Here is how I create it

 <Select name="fieldcombo"
               value={this.state.comboFieldValue}
               onChange={this.handleFieldComboChange.bind(this)}
               simpleValue
               openOnClick={false}                    
               clearable={true}
               options={selectData}
                />
