Ng-model has clear data

Hello sir,
I have used input fied like

 input type="text" ng-model="select.item"   value={{singlePartyitemSelectedValue}}>. 

i would like to input value or search to set value to input field. But when i search from modal and set value to inputfield. when i select the value it will remain blank if i use ng-model. But it i would like to use both ng-model and value.
Here is my screen shot


Have you tried ng-value?
