Material.SetFloat not updating.

I'm trying to update _Fill property of my shader using Material.SetFloat property. It works just fine, however it's not updating in play-mode but only after stopping.

My script

 public class OrbFillUpdater : MonoBehaviour
 {
     public IntegerReference Variable;
     public IntegerReference Max;

     private Material material;

     private void Start()
     {
         material = GetComponent<Image>().material;
     }

     private void Update()
     {
         float value = Mathf.Clamp01(Mathf.InverseLerp(0, Max.Value, Variable.Value));
         material.SetFloat("_Fill", value);
     }
 }

And here is _Fill property.

 _Fill("Fill Amount", Range(0, 1)) = 1

 float _Fill;

 fixed4 frag(v2f IN) : SV_Target {
     // ... Code
     if (IN.texcoord.y >= _Fill)
     {
         if (IN.texcoord.y + (noise.r - 0.7) * _NoiseStrength >= _Fill)
         {
             color.a = 0;
             layer1.a = 0;
             layer2.a = 0;
             layer3.a = 0;
         }
     }
 }
