angularjs - Make a dynamic function on ng-click -

i have button this

<button ng-click="method = 'create'; title = 'create'>create</button> <button ng-click="method = 'update'; title = 'update'>update</button>

and this

<button ng-click="create(param)">{{ title }}</button> <button ng-click="update(param)">{{ title }}</button>

code above works fine, want make dynamic.

so change following.

<button ng-click="{{ method }}(param)">{{ title }}</button>

this not work, dont know why, although if inspect element, code above generates corrects code mentioned before.

<button ng-click="this[method](param)">{{ title }}</button>

this points current scope object this[method] can access method via variable name.
